Need a few explanations/ viewpoints on a few things

Hey everyone. I’ve been lurking this sub for years, and for the most part, love it. I generally agree with a good portion of the opinions in here and appreciate the effort that people in here put into posting and researching.
Over time as I read about more things in here, there are things I don’t understand, or am curious about.
  1. To start, I wholeheartedly support the 2nd amendment, and believe we should be able to have guns. With the whole idea of martial law and societal chaos possibly happening, I can’t help but wonder, what is having a gun really going to do for us? I know that sounds like I’m “anti gun” but that’s not how I mean it to sound. I mean to say that say supposedly some person with power(politician, billionaire, whatever,) wants me dead. If I have a gun or 3 in my house, they could easily send 2 highly trained military people with unlimited weapons to easily wipe me out.
  2. I don’t fully understand what a virtual currency (bitcoin etc.) is and how it differs from what we have now. To me, aside from the 8 dollars in my wallet and the 20 dollars my grandma decides to give me here and there, our currency is already virtual. I work x amount of hours and I look at a screen that tells me that my bank account has Z amount of dollars in it, but I don’t actually physically have that amount of money. I understand that obviously I could withdraw it in cash if I wanted, which is almost pointless in this day and age. So I guess what I’m asking is what is the difference between our system now of online banking, and the future “virtual currency” that people worry about.
Again, please don’t read these as me saying” what’s the point in believing____”. I’m genuinely curious as to why we believe in these rights/ concepts.

Some Basics Of Bitcoin

For someone not familiar with Bitcoin, the first question that comes to mind is, "What is Bitcoin?" And another common question that is often asked relates to the Bitcoin price. It started out a under 10 cents per Bitcoin upon its introduction in early 2009. It has risen steadily since and has hovered around $4000 per Bitcoin recently. So regarding Bitcoin value or the Bitcoin rate this is a most remarkable appreciation of value and has created many, many millionaires over the last eight years.
The Bitcoin market is worldwide and the citizens of China and Japan have been particularly active in its purchase along with other Asian countries. However, recently in Bitcoin news the Chinese government has tried to suppress its activity in that country. That action drove the value of Bitcoin down for a short time but it soon surged back and is now close to its previous value.
The Bitcoin history chart is very interesting. Its creator was an anonymous group of brilliant mathematicians (using the pseudonym Satoski Nakamoto) who designed it in 2008 to be "virtual gold" and released the first Bitcoin software in early 2009 during the height of the USA economic crisis. They knew that to have lasting value, it like gold had to have a finite supply. So in creating it they capped the supply at 21 million Bitcoin.
Bitcoin mining refers to the process by which new Bitcoin is created. With conventional currency, government decides when and where to print and distribute it. With Bitcoin, "miners" use special software to solve complex mathematical problems and are issued a certain number of Bitcoin in return.
A question that then arises is, is Bitcoin mining worth it. The answer is NO for the average person. It takes very sophisticated knowledge and a powerful computer system and this combination of factors makes it unattainable for the masses. This applies even more to bitcoin mining 2017 than in past years.
Many wonder, who accepts Bitcoin? This question gets asked in various ways, what are stores that accept bitcoin, what are websites that accept bitcoins, what are some retailers that accept bitcoin, what are some places that accept bitcoin and where can I spend bitcoin.
More and more companies are beginning to see the value of accepting cryptocurrencies as a valid payment option. Some major companies that do are DISH network, Microsoft, Expedia, Shopify stores, Newegg, Payza, 2Pay4You, and others.Two major holdouts at this time are Walmart and Amazon.
Ethereum is the strongest rival to Bitcoin in the cryptocurrency market and many wonder at the question of Bitcoin vs Ethereum. Ethereum was created in mid-2015 and has gained some popularity but still ranks far behind Bitcoin in usage, acceptance and value.
A question that often comes up often relates to Bitcoin scam. This author has a friend who made a purchase from a company that promised 1-2% growth per day. The company website listed no contact information and after a couple months the website simply vanished one day and my friend lost all the money he had invested which was several thousand dollars.
One has to know how to buy Bitcoins, how to purchase Bitcoin or how to buy Bitcoin with credit card in order to get started. Coinbase is a very popular site to do this. Their fee is 3.75% and the buying limit is $10,000 per day. This would probably be the easiest way to buy bitcoins.
Others would like to buy Bitcoin with debit card. Coinbase also provides this service and has clear step by step instructions on how to proceed with either your debit or credit card.
There are those who would like to buy Bitcoin instantly. This can be done at Paxful, Inc. and can be done through W. Union or any credit/debit card.
Other common questions that come up are what is the best way to buy Bitcoins, the best way to get bitcoins or where to buy bitcoins online. The easiest way is probably to purchase it through a digital asset exchange like the previously mentioned Coinbase. Opening an account with them is painless and once you link your bank account with them you can buy and sell Bitcoin quite easily. This is quite likely also the best place to buy Bitcoins.
One must know what a Bitcoin wallet is and how to use it. It is simply the Bitcoin equivalent of a bank account. It allows you to receive Bitcoins, store them and send them to others. What it does is store a collection of Bitcoin privacy keys. Typically it is encrypted with a password or otherwise protected from unauthorized access.
There are several types of digital wallets to choose from. A web wallet allows you to send, receive and store Bitcoin though your web browser. Another type is a desktop wallet and here the wallet software is stored directly on your computer. There are also mobile wallets which are designed for use by a mobile device.
A question that occasionally comes up is that of Bitcoin stock or how to buy Bitcoin stock. By far the most common way to proceed in this area is to buy Bitcoin directly and not its stock.
There is one entity called Bitcoin Investment trust which is an investment fund that is designed to track the market flow of Bitcoin. Some analysts however are calling this a risky way to become involved in this marketplace.
The Bitcoin exchange rate USD is a closely watched benchmark both on a daily basis and long term over the last 8 years since its introduction to the world's financial marketplace. A popular company to receive the most current rate in Bitcoin valuation is XE. They show Bitcoin to USD valuation and also the complete Bitcoin price chart, the Bitcoin value chart and the Bitcoin to USD chart. If you ask, "How much is one Bitcoin?" you will always know from their continuously updated charts.
Similar questions that come up in this area relate to the bitcoin rate history, the bitcoin price chart live, the bitcoin to dollar exchange rate, the bitcoin dollar chart and the bitcoin 5 year chart. The previously mentioned website, xe, is also a good source for answers to these questions.
Regarding Bitcoin cash, ie. to get USD from selling Bitcoin, Bitwol is one company that enables you to do this. WikiHow is another company that will take you through this process.

Why UMI is a Step toward a Free Financial World

Why UMI is a Step toward a Free Financial World

https://preview.redd.it/sk4qzvg2o5p51.jpg?width=1024&format=pjpg&auto=webp&s=42c422967888ffb44288e1cf7b8e9b4ffd6e20a1
Quite recently, the world has seen a remarkable event — an anonymous bitcoin whale sent a total of $2.24 billion in a series of transactions. Large transactions are certainly not uncommon for the bitcoin network. Whale Alert — blockchain tracker and analytics system — regularly reports large and interesting transactions. Although $2.24 billion is the largest ever cryptocurrency transfer, the most remarkable thing about this event is not the transfer amount but the incredibly little fee the sender paid for the transaction — less than $1. With no checkups and intermediaries.
If such a transfer had happened a few years ago, it would have considered abnormal and unreal. Today it is a matter of fact. With each passing day, using cryptocurrency for making transfers is getting more attractive than bank transfers. The UMI network, which enables instant payments with no fees, fits in best with new realities. Let's explore this issue.
Freedom from Bank Charges
The BTC whale sent the above-mentioned amount in seven successive transactions within one hour. The total amount was 241,500 BTC, which was equivalent to $2.24 bln. Each transfer cost around 0.0001 BTC or just $0.93, giving a total of about $6.51 for the seven transfers.
Let's compare now how much you would be charged for an identical transfer in a bank.
In big banks, the international transfer fee is at least 1% of the amount, but it is often higher than that depending on the conditions. For instance, the VISA system charges 1 to 10% of the transaction amount for an international transfer (minimum of $10). Therefore, the more you transfer, the more you pay for it. To transfer the above-mentioned amount via a bank, a customer would have to part with as much as $22.4 mln (!!!), in the best-case scenario — that is if the fee is the minimum 1%. In other words, a bank would make a fortune — virtually at the drop of a hat, making no effort whatsoever — by simply taking someone's money. What makes it more absurd is that banks intend to further raise their fees amid coronavirus pandemic.
Cryptocurrencies are a completely different story. In most cryptocurrency networks, fees do not depend on the transaction amount — the same fee could be charged for transferring $1 or $1 bln. In the cryptocurrency world, it doesn't matter how much money you transfer. If you make a big transfer, no one makes you pay the “tithe”. With UMI, you don't have to pay anything to anyone — not a dime. But we'll get back to this a little later.
Freedom from Excessive Limits and Unneeded Checkups
First, let's consider another important factor — the very possibility to make unhindered transfers of large amounts via bank especially foreign transfers. The irony is that even if someone chooses to pay this multi-million dollar fee, the transfer would far from being 100% successful.
In most countries, including the Russian Federation, a $22 bln transaction would be virtually impossible to run in a state-owned bank, let alone private banks. Even going through a bunch of mandatory procedures as well as wasting lots of nerves and time wouldn't save the day. This is why a payment of this size is virtually impossible:
  1. The overwhelming majority of the world's banks just don't happen to have such large amounts on their correspondent accounts. Even if we assume they do have sufficient funds on the books, this money doesn't just sit idle — bankers use it in their own favor, for instance, to grant loans, make deposit payments, etc. No bank would agree to send all its reserve funds to another bank on your orders. Moreover, banks have no right to violate the law in terms of reserve requirements, including currency norms. And processing such a large amount contradicts the established rules and regulations. So, even if money is technically recorded on the customer's account, transferring it to another bank, especially in a foreign country, is still a virtually impossible task.
  2. In almost all states transactions of this scale are only allowed on the level of governments, the International Monetary Fund, the World Bank, or mega-tycoons with a declared multi-billion dollar income, such as Bill Gates, Warren Buffett, and the like. In other words, only customers with a special status can make especially large transfers without restrictions. Any “abnormal” transactions fall under suspicion and automatically frozen. If you have always run $500 transactions on a monthly basis, any incoming or outgoing $10,000 transfer would most probably be frozen. Let alone billions of dollars. An average owner of a large business will only be allowed to transfer billions of dollars after they get approval from FATF on an individual basis. Obviously, they must also be verified using KYC (Know Your Customer) and AML (Anti-money laundering) procedures and must establish the provenance of each dime they transfer. They have to do all this to transfer THEIR money, with a huge fee of billions of dollars.
  3. The situation is even worse because it is equally true for receiving monetary transfers. In other words, if you have a large amount successfully transferred to you, there is no guarantee that you can use this money. Sadly, even if the money leaves the sender's bank, the recipient's bank can instantly freeze it. On the very same day, you could get a visit from bank or government officials along with the state security service and a special interrogation. If you cannot provide provenance data for the funds, the transfer could easily remain frozen for good. Naturally, this system opens the doors for various types of abuse of power and manipulation by bankers, governments, and state services.
For the existing banking system, any big transaction makes you a suspect of some manipulations resulting in a frozen transfer. More importantly, it isn't only true for multi-billion or multi-million transfers. Any transaction involving hundreds of thousands, dozens of thousands, or simply thousands of dollars may be deemed suspicious and sanctioned. It means that anyone who runs relatively big transactions runs the risk of encountering certain problems at any time.
Cryptocurrencies are a step toward free transfers
The above-described situation proves that digital money helps people get rid of many problems related to bank transfers: high fees, payment amount limits, specification of personal data, verification procedures. With digital money, you don't have to prove or explain anything. This is a real revolution that makes people free from fees and manipulation. Cryptocurrencies allow people to be a master of their funds and no one has the power to change this. No one charges you crazy fees and no one can steal your coins.
With each passing minute, cryptocurrencies are becoming part of our life, and rather than profit from trading, investment, mining, or staking, they are regarded as a convenient way of sending funds. Only cryptocurrencies make people feel completely safe and allow them to transfer whatever amount wherever they want. This is a huge step towards changing the existing financial system, and it has already been made.
But UMI Goes Even Further
It may appear that problem with bank fees concerns only large businessmen. In real fact, regular people living live paycheck to paycheck are more sensitive to this issue. Being on a tight budget, most people have to pay for any bank transaction.
You always pay fees charged by banks — when you pay utility bills, buy online, deposit money to your bank card, receive money, transfer money between your accounts or withdraw cash from an ATM. Overall, bank fees cost people a lot of money. It's curious to know how much your pay banks every year for mediation.
Now let's see how you can make transactions using UMI.
In terms of fees, UMI is more profitable than banks and even more profitable than most of the other cryptocurrencies, including bitcoin. There are no fees in the UMI network at all, even hidden ones. All transactions are instant. That is, if you sent $2.24 billion through the UMI network, it would be instant and completely free. There are no limits, verifications, and other nervous procedures. Instant, free, and secure — here and now.
This is the key advantage of UMI as a payment instrument. Our cryptocurrency empowers all people — from large businessmen to factory workers — with profitable and absolutely safe funds transfers. UMI gives all people around the globe equal opportunities. This is the next step toward a free financial world. We are the first to make it.
Sincerely yours, UMI team

Recap on CoinEx & Avalanche AMA Aug 5, 2020

Recap on CoinEx & Avalanche AMA Aug 5, 2020
Written by SatoshisAngels
Published by read.cash
On August 5th 2020, Satoshi’s Angels hosted an AMA for CoinEx on “How BCH and Avalanche Are Bringing Financial Freedom to 6 Billion People” on a Chinese platform Bihu. During the 100-minute event, Haipo Yang of ViaBTC and CoinEx, and Emin Gun Sirer of AVA Labs shared their in-depth views on such topics as different consensus mechanisms, community governance, IPFS, Defi. And Haipo explained why he wants to fork BCH. This is the full text.
You can check out the full AMA here (mostly in Chinese with some English translation).

https://preview.redd.it/x790bw58axf51.png?width=1920&format=png&auto=webp&s=03c8af942f8f14d98d5dd693adf9e2a50448d61d
Cindy Wang (Satoshi’s Angels): There are news saying that you are to fork BCH. Is it a marketing makeover? Are you serious about it?
Haipo Yang: It’s definitely not a marketing makeover. But the details are not decided yet.
Over the past three years, the BCH community has gone through multiple discussions from reducing block time, changing mining algorithms, adding smart contracts, etc. But none of these disputes have been well settled.
BCH is a big failure in terms of governance. A lack of good governance has made it fall in disorder. It is too decentralized to make progress.
You may know that the first BCH block was mined by ViaBTC. And we gave a lot of support to it indeed. But we didn’t dominate the fork. The Chinese community in particular thought I had a lot of influence, but it was not true.
I think the whole community is very dissatisfied with Bitcoin ABC, but it is difficult to replace them or change the status quo. So I am thinking of creating a new branch of BCH. The idea is still in early stage. I welcome anyone interested to participate and discuss it with me.
Wang: Professor Emin, what’s your attitude to fork? Do you think it’s a good timing to fork BCH?
Emin Gun Sirer: I am a big fan of BCH. It adheres to the original vision of Satoshi Nakamoto. I like the technical roadmap of BCH. But just like what Haipo mentioned, BCH lacks a good governance mechanism. There are always something that can cause BCH community to divide itself.
But I think it’s not enough to just have a good governance mechanism. There are many good proposals in the community but failed to be adopted in the end. I think BCH needs social leadership to encourage discussion when there are new proposals.
Wang: We are all curious to know How Avalanche got its name?
I know that Avalanche doesn’t mean well in Chinese. But in English, it’s a very powerful word. Avalanche represents a series of algorithms piling together like a mountain. When decisions slowly form, the ball (nodes in the network) on top of the mountain starts going down the hill on one side, and it gets bigger and bigger, and like an avalanche and it becomes unstoppable, making the transaction final.
Wang: Prof. Emin, I know that you are a big blocker. Have you ever considered implementing Avalanche based on BCH? Why create another chain?
Sirer: Of course I considered that. Satoshi Nakamoto consensus is wonderful, but the proof-of-work mechanism and Nakamoto consensus base protocols have some shortcomings, such as network latency, and it is hard to scale. Avalanche, instead, is totally different, and is the new biggest breakthrough in the past 45 years. It is flexible, fast, and scalable. I’d love to implement BCH on top of avalanche in the future, to make BCH even better by making 0-conf transactions much more secure.
Wang: As an old miner, why did CoinEx Chain choose to “abandon” POW, and turn to POS mechanism?
Haipo: Both POW and POS consensus algorithms have their own advantages. POW is not just a consensus algorithm, but also a more transparent and open distribution method of digital currency. Anyone can participate in it through mining.
POW is fairer. For a POS-based network, participants must have coins. For example, you need to invest ICO projects to obtain coins. But developers can get a lot of coins almost for free. In addition, POW is more open. Anyone can participate without holding tokens. For example, as long as you have a computer and mining rigs, you can participate in mining. Openness and fairness are two great features of POW. POS is more advanced, safe and efficient.
POS is jointly maintained by the token holders, and there is no problem of 51% attacks. Those who hold tokens are more inclined to protect the network than to destroy the network for their own interests. To disrupt the network, you need to buy at least two-thirds of the token, which is very difficult to achieve. And when you actually hold so many coins, it’s barely possible for you to destroy the network.
POW has the problem of 51% attack. For example, ETC just suffered the 51% attack on August 3. And the cost to do that is very low. It can be reorganized with only tens of thousands of dollars. This is also a defect of POW.
In addition, in terms of TPS and block speed, POS can achieve second-level speed and higher TPS. Therefore, CoinEx Chain chose POS because it can bring a faster transaction experience. This is very important for decentralized exchanges. Both POW and POS have their own advantages. It’s a matter of personal choice. When choosing a consensus mechanism, the choice must be made according to the characteristics of the specific project.
https://preview.redd.it/upbayijaaxf51.jpg?width=1055&format=pjpg&auto=webp&s=703e3b6a493a76f86bc9045e784d174bde9d3c42
Wang: Ethereum is switching to ETH 2.0. If they succeed, do you think it will lead the next bull market?
Sirer: If Ethereum 2.0 can be realized, it must be a huge success.
But I doubt it can be launched anytime soon considering that it has been constantly delayed. And even if it comes out, I am not so sure if it will address the core scaling problem. And the main technology in Ethereum 2.0 is sharding. Sharding technology divides the Ethereum networks into small parallel groups, but I think what will happen is everyone wants to be in the same “shard” so the sharding advantages might not be realizable in Ethereum 2.0.
Avalanche supports Ethereum’s virtual machine, and Avalanche can realize 1 second level confirmation, while with sharding finalizing confirmation takes 5–6 seconds at best. Avalanche approach to make Ethereum scale is superior to Ethereum 2.0. There are many big players behind Ethereum 2.0, and I wish them success. But I believe that Avalanche will be the fastest and best Smart Contract platform in the crypto space, and it is compatible with Ethereum.
Wang: Why is Avalanche a real breakthrough?
Sirer: Avalanche is fundamentally different from previous consensus mechanisms. It’s very fast with TPS surpasses 6500, which is three times that of VISA. Six confirmations can be achieved in one second. Compared with the POW mechanism of Bitcoin and Bitcoin Cash, Avalanche’s participation threshold is very low. It allows multiple virtual machines to be built on the Avalanche protocol.
Avalanche is not created to compete with Bitcoin or fiat currencies such as the US dollar and RMB. It’s not made to compete with Ethereum, which is defined as the “world’s computer”. Avalanche is positioned to be an asset issuance platform to tokenize assets in the real world.
Wang: How do you rank the importance of community, development, governance, and technology to a public chain?
Sirer: These four are like the legs of a table. Every foot is very important. The table cannot stand without strong support.
A good community needs to be open to welcome developers and people. Good governance is especially important, to figure out what users need and respect their voices. Development needs to be decentralized. Avalanche has developers all over the world. And it has big companies building on top of Avalanche.
Yang: From a long-term perspective, I think governance is the most important thing, which is the same as running a company.
In the long run, technology is not important. Blockchain technology is developed based on an open source softwares that are free to the community. Community is also not the most important factor.
I think the most important thing is governance. Decentralization is more about technical. For example, Bitcoin, through a decentralized network method, ensures the openness and transparency of data assets, and the data on the chain cannot be tampered with, ensuring that the total amount of coins has a fixed upper limit.
But at the governance level, all coins are centralized at some degree. For example, BCH developers can decide to modify the protocol. In a sense, it is the same as managing a company.
Historically, the reasons for the success and failure of companies all stem from bad governance. For example, Apple succeeded based on Steve Jobs’s charisma, leadership and the pursuit of user experience. When Jobs was kicked out, Apple suffered great losses. After Jobs returned, he made Apple great again.
Issues behind Bitmain is also about governance. Simply put, governance requires leaders who have a longer-term vision and are more capable of coordinating and balancing the resources and interests of all parties to lead the community.
In the blockchain world, many people focus on technology. In fact, technology is not enough to make great products. User experience is most important. Users don’t care about the blockchain technology itself, but more concerned about whether it is easy to use and whether it can solve my problem.
We need to figure out how to deliver a product like Apple. The pursuit of user experience is also governance in nature. And governance itself lies in the soul of key leaders in the community.
Realize tokenization of assets in.
https://preview.redd.it/14jf1bvcaxf51.jpg?width=1082&format=pjpg&auto=webp&s=c312912142c38de986f42912086e205354162190
Wang: Speaking of asset tokenization, I would like to ask Haipo, do you think the market for assets on the chain is big?
Yang: It must be very big. We need to see which assets can be tokenized.
Assets that can be tokenized are standardized assets, sush as currencies and securities.
  1. In terms of currency, Tether has issued over 10 billion U.S. dollars. Many people think that’s too much. But I think this market is underestimated. The market for stablecoins in the future must be hundreds of billions or even trillions, especially after the release of Facebook’s Libra. Even US dollar might be issued based on the blockchain in the future.
At present, the settlement of USD currency is through the SWIFT system. But the SWIFT system itself is only a clearing network, a messaging system, not a settlement network. It takes a long time for clearing and settlement, and it is not reliable. But both USDT and USDC can quickly realize cross-border transfers in seconds and realize asset delivery. Even sovereign currencies are likely to be issued on the blockchain. I believe RMB also has such a plan.
  1. Equity and securities markets are the largest market. But they have strict requirements for market access.
Whether a stock is listed on A-shares or in the American markets, it’s hard to obtain them. I believe that the blockchain can completely release the demand through decentralization. It can allow any tiny company or even a project to issue, circulate and finance a token.
There may be only tens of thousands of stocks currently traded globally. There are also tens of thousands of tokens in the crypto space. I believe that millions or more of assets will be traded and circulated in the future. This can only be realized through decentralized technology and organization.
The market for assets tokenization will be huge. And at present, the entire blockchain technology is still very primitive. Bitcoin and Ethereum only have a few or a dozen TPS, which is far from meeting market demand. This is why CoinEx is committed to building a decentralized Dex public chain.
Wang: Avalanche’s paper was first published on IPFS. What do you think of IPFS?
Sirer: I personally like IPFS very much. It is a decentralized storage solution.
Yang: There is no doubt that IPFS solves the problem of decentralized storage, and can be robust in the blockchain world, and can replace HPPT services. But there are still three problems:
  1. IPFS is not for ordinary users. Everybody needs BCH and BTC, but only developers need IPFS, which is a relatively niche market;
  2. IPFS is more expensive than traditional storage solutions, which further reduces its practicality. In order to achieve decentralization, more copies must be stored, and more hardware devices must be consumed. In the end, these costs will be on to users.
  3. There may be compliance issues. If you use IPFS to store sensitive information, such as info from WikiLeaks, it may end up threatening national security. I doubt that decentralized storage and decentralized public chains can survive under the joint pressure of global governments.
The IPFS project solves certain problems. But from the perspective of application prospects, I am pessimistic.
Wang: What do you think of Defi?
Yang: I want to talk about the concept first.
Broadly speaking, the entire blockchain industry is DeFi in nature. Blockchain is to realize the circulation of currency, equity, and asset value through decentralization.
So in a broad sense, blockchain itself is DeFi. In a narrow sense, DeFi is a financial agreement based on smart contracts. DeFi, through smart contracts, can build applications more flexibly. For example, before we could only use Bitcoin to transfer and pay. Now with smart contracts, flexible functions such as lending, exchange, mortgage , etc. are available. The entire blockchain industry is gradually evolving under the conditions of DeFi. DeFi will definitely get greater development in the future.
Sirer: I think Defi will definitely have a huge impact. DeFi is not only an innovation in the cryptocurrency field, but also an innovation in the financial field. Wall Street companies have stagnated for years with no innovation. Avalanche fits different DeFi needs, including performance and compliance. In the future, not only will Wall Street simply adopt DeFi, but DeFi will grow into a huge market that will eventually replace the traditional financial system.
Questions from the community:
1. How does Avalanche integrate with DeFi?
Sirer: At present, all DeFi applications on Avalanche have surpassed Ethereum. What can be achieved on Ethereum can be achieved on Avalanche with better user experience. We are currently connecting with popular DeFi projects such as Compound and MakerDao to add part of or all of their functions.
At present, Avalanche is working on decentralized exchange (DEX). The current DEXs are limited by speed and performance but when they are built on top of Avalanche it will be real-time and very fast.
2. How many developers does BCH have?
Yang: I think it does not matter how many developers there are. What matters is what should be developed. I watched Jobs’ video the other day, and it inspired me a lot. We are not piecing together technology to see what technology can do. It’s we figure out what we want first and then we use the technology we need.
The entire blockchain community worship developers. Such as they call Vitalik “V God”. It’s not necessary to treat developers as wizards. Developers are programmers, and I myself is also a programmer.
ViaBTC has a development team of over 100 people, including core members from Copernicus (a dev team formerly belonged to Bitmain). Technically we are very confident to build faster, stabler, and better user experience products.

Blockchain in the Public Sector – Webcast Q&A

Blockchain in the Public Sector – Webcast Q&A
Link to our website: https://block.co/blockchain-in-the-public-sector-webcast-qa/
Block.co fourth webcast titled "Digital Transformation of the Public Sector & The Upcoming Legislation of Blockchain Technology in Cyprus” was an immense success. We gathered some of the best experts in the field, Deputy Minister Kyriacos Kokkinos, Jeff Bandman, Steve Tendon, and Christiana Aristidou to share their experience and discuss with us the latest updates regarding Blockchain in the Public Sector.
In its fourth series of webcasts, Block.co gathered 281 people watching the event from 41 different countries, for a two-hour webcast where guests answered participants’ questions. Following the impressive outcome and response we received from the audience, Block.co’s team has done its best to address all the questions for which public information is available.
Below is a list of the questions that were made and were not answered due to time constraints during the webcast. For the remaining questions from our audience, the team will reach out to our distinguished guests to receive their comments and feedback. Please note, that the below information is only for informational purposes!
Question 1:
How can asset tracing be accomplished with bitcoins and cryptocurrency? And how can this be regulated?
Block.co Team Answer:
Digital Asset tracing may be accomplished with cryptocurrency intelligence solutions such as Cipher Trace and the ICE cryptocurrency intelligence program. FATF (Financial Action Task Force) embarked on a program of work from summer 2018 to June 2019 to strengthen and update the provisions dealing with virtual assets and virtual asset service providers. FATF updated Recommendations in October 2018 and Guidance in June 2019 include several new obligations that apply to VASPs. The so-called “Travel Rule” FATF announced in October 2019 agreed on the assessment criteria for how it will assess countries’ compliance with the new global standards. Under the Travel Rule, the transmitter’s financial institutions must include and send information in the transmittal order such as Information about the identity, name, address, and account number of the sender and its financial institution Information about the identity, name, address and account number of the recipient. The ”Travel Rule” is effectively being applied to cryptoasset transfers when there is a virtual asset service provider (VASP) involved. The scope of focus has broadened from “convertible” virtual assets to any virtual asset. Countries should make sure businesses can freeze crypto wallet or exchange accounts for sanctioned individuals.
Question 2:
Which kind of software or technical knowledge is required to develop cryptocurrency?
Block.co Team Answer:
It depends on the type of cryptocurrency you wish to create, as well as the preferred functionality and features, and characteristics of the token or coin (i.e. will it be pre-mined, what type of hashing or cryptographic algorithm will be used (i.e. proof of work (POW) or proof of stake (POS) or a hybrid of both), etc. Likewise, it is useful to utilize a programming language that is broadly used and supported by a vast and active development community; more data could be found here: more information could be found here: top programming languages in 2015/2016, published by IEEE here, and TIOBE. Hypothetically, you can utilize any programming language to make cryptocurrency digital money, however, the most widely recognized are C, C++, Java, Python, Perl. The beauty of cryptocurrencies is that you can literally have access to the entire Bitcoin and Ethereum open-source programming scripts, and create your alternate coin (altcoin).
Question 3:
Hello all, I want to know about the current status of the European Union Blockchain initiative in currency or public identity.
Block.co Team Answer:
Please refer to the European Services Blockchain Infrastructure (EBSI) website.
Question 4:
Mining is also the process of confirmation of transactions in the Bitcoin Blockchain. What is the process of confirmation of transactions in the Blockchain of an Organization? How do we call it?
Block.co Team Answer:
That would depend on the specific consensus algorithm used for the confirmation of transactions. The consensus algorithm is part of the blockchain protocol that defines the rules on how consensus is reached on that blockchain. In order to participate, entities on the blockchain must obey and follow the same consensus algorithm. Make sure to check our glossary for more information.
Question 5:
How does a small business implement blockchain into its current non-blockchain software systems? Who do they hire to install it?
Block.co Team Answer:
It is easy when there are APIs to connect the various software. For more information, you can check Block.co API.
Question 6:
What is your opinion on digitizing developing economies like India by using AI and blockchain?
Block.co Team Answer:
Watch a very interesting webinar on the matter by Mr. Prasanna:
Question 7:
Blockchain technologies have been around since 2008. What would you say has been the biggest obstacle in widespread adoption?
Block.co Team Answer:
In our opinion, the biggest obstacles are volatile cryptoasset prices, complicated UIs, undefined blockchain technology standards. Moreover, the legislation around the technologies is still now being developed and does not offer legal certainty for broader adoption.
Question 8:
Limitations to Blockchain Usability in the Public Sector?
Block.co Team Answer:
Blockchain in the Public Sector, like any other innovative concept with big potential, cannot be a solution to every problem. Users and developers are still figuring out technological and managerial challenges. From a technological perspective, some aspects such as platform scalability, validation methods, data standardization, and systems integration must still be addressed. From a managerial point of view, the questions include business model transformation, incentive structure, and transaction scale, and maturity. Read more here.
Question 9:
How can these blockchain initiatives be practical for the African context
Block.co Team Answer:
As long as the internet infrastructure is in place, these blockchain initiatives may have the same benefits for the African region.
Question 10:
What are some compelling use cases you’ve seen lately, and how do they serve to further legitimize blockchain as a solution?
Block.co Team Answer:
You can see the global trends from all around the world when it comes to further legitimization as a solution, with China leading the way. Read more here.
Question 11:
How does digital currency manage the issue of money laundering?
Block.co Team Answer:
Depends under which context you are looking at the term digital currency. A digital currency usually refers to a balance or a record stored in a distributed database, in an electronic computer database, within digital files or a stored-value card. Some examples of digital currencies are cryptocurrencies, virtual currencies, central bank digital currencies (CBDCs), and e-Cash. The Financial Action Task Force (FATF) is an intergovernmental body established in 1989 on the initiative of the G7 to develop policies to fight money laundering. Since 2001 FATF is also looking into terrorism financing. The objectives of FATF are to set standards and promote effective implementation of legal, regulatory and operational measures for combating money laundering, terrorist financing, and other related threats to the integrity of the international financial system. FATF is a “policy-making body” that works to generate the necessary political will to bring about national legislative and regulatory reforms in these areas. FATF monitors progress in implementing its Recommendations through “peer reviews” (“mutual evaluations”) of member countries. It is the global watchdog for anti-money laundering & counter-terrorist finance. In June 2019, it updated its guidance paper for Virtual Assets Service Providers (VASPs) regarding the transfer of digital assets. There was an insertion of a new interpretive note that sets out the application of the FATF Standards to virtual asset activities and service providers. To apply FATF Recommendations, countries should consider virtual assets as “property,” “proceeds,” “funds,” “funds or other assets,” or other “corresponding value.” Countries should apply the relevant measures under the FATF Recommendations to virtual assets and virtual asset service providers (VASPs). Read more about the FATF recommendations here).

Question 12:
To what extent can blockchain be used to improve the privacy of healthcare?
Block.co team Answer:
Please refer to our previous webcast, blog, and articles for more information.
Question 13:
What is Blockchain technology in Shipping?
Block.co team Answer:
The shipping sector has been in the hold of phony maritime institutes charging exorbitant fees via agents, issuing certificates to candidates who do not have the imperative attendance, or those candidates who just pay the fees for the course and ask for the certificate. In view of these fake accreditations, the possibility exists that someone could be harmed or killed, and we could face any number of potential ecological disasters. Having the option to easily verify the genuine origin of a certificate by an approved maritime center is foremost for shipping companies to fast-track their operation and streamline their labor.
Question 14:
Different uses of blockchain other than cryptocurrency?
Block.co team Answer:
Please refer to our blog and glossary.
Question 15:
Upcoming trends in Blockchain concerning Advertising, Marketing, and Public Relations in the Public and Private sectors.
Block.co Team Answer:
Regarding the application of blockchain technology to media copyrights, please see Block.co use case proposal during the Bloomen Ideathon.

Question 16:
How to create a decentralized blockchain?
Block.co Team Answer:
An excessive number of individuals feel that blockchain is some supernatural innovation that makes up a decentralized system. In truth, this innovation only enables decentralization. Which means, it permits cryptocurrency to work in a decentralized way. Yet, it doesn’t give any guarantees that it will work that way. Along these lines, it’s really, some outer variables that decide genuine decentralization. Technology, itself never really guarantees it. That is the reason it’s a mistake to expect that if it’s a blockchain — it’s decentralized. From a technical perspective, both blockchains, centralized, and decentralized are comparative, as they take work on distributed peer to peer to network. This implies every node is individually responsible to verify and store the shared ledger. Both Blockchains utilize either a proof-of-work or proof-of-stake mechanisms to make a solitary record and they have to give upper and lower limits on the security and productivity of the system. For more information please refer to our infographic.
Question 17:
Dubai government Blockchain implementation progress?
Block.co Team Answer:
You can see more information here.
Question 18:
How Blockchain and IoT can be integrated to secure data being transmitted through IoT devices.
Block.co Team Answer:
You can read more about it here.
Question 19:
How can the Nigerian government use Blockchain to effectively implement its existing launched eGovernment master plan?
Block.co Team Answer:
Perhaps it can draw its attention to the initiatives of Dubai, Estonia, and Malta to prepare an implementation framework.
Question 20:
What impact is blockchain going to have in today world of business especially in the financial sector
Block.co Team Answer:
Please refer to our recent article titled Benefits of Blockchain Technology in the Banking Industry.
Question 21:
Is Blockchain Technology affect individuals?
Block.co Team Answer:
The social effect of blockchain innovation has just started to be acknowledged and this may simply be a hint of something larger. Cryptocurrencies have raised questions over financial services through digital wallets, and while considering that there are in excess of 3,5 billion individuals on the planet today without access to banking, such a move is surely impactful. Maybe the move for cryptocurrencies will be simpler for developing nations than the process of fiat cash and credit cards. It is like the transformation that developing nations had with mobile phones. It was simpler to acquire mass amounts of mobile phones than to supply another infrastructure for landlines telephones. In addition to giving the underprivileged access to banking services, greater transparency could also raise the profile and effectiveness of charities working in developing countries that fall under corrupt or manipulative governments.
An expanded degree of trust in where the cash goes and whose advantages would without a doubt lead to expanded commitments and backing for the poor in parts of the world that are in urgent need of help. Blockchain technology is well placed to remove the possibility of vote-apparatus and the entirety of different negatives related to the current democratic procedure. Obviously, with new innovation, there are new obstacles and issues that will arise, yet the cycle goes on and those new issues will be comprehended with progressively modern arrangements. A decentralized record would give the entirety of the fundamental information to precisely record votes on an anonymous basis, and check the exactness and whether there had been any manipulation of the voting procedure.
Question 22:
As Andreas Antonopoulos often says in his MOOC: ”is a blockchain even needed?” Ie. Are there better methods?
Block.co Team Answer:
In combination with nascent technologies, IoT, distributed computing, and distributed ledger technologies, governments can provide inventive services and answers for the citizens and local municipalities. Blockchain can provide the component to create a safe framework to deal with these functions. In particular, it can provide a safe interoperable infrastructure that permits all smart city services and capacities to work past presently imagined levels. On the off chance that there were better techniques, they would be researched.
Question 23:
Would any of this be also applicable to the educational sector (as part of the general public sector), and if so in which way?
Block.co Team Answer:
Yes, please refer to our Webcast on Education and our blog post.
Question 24:
Will we be able to get a hold of this recording upon completion of the meeting?
Block.co Team Answer:
Yes, here is a link to the recording of our webcast Blockchain in the Public Sector.
Question 25:
Was wondering if there are any existing universal framework in governing the blockchain technology?
Block.co Team Answer:
The short answer is NO, as this framework is currently being prepared in collaboration with the various Member States.

PoW or PoS: The Difference Between Mined and Non-Mined Crypto

PoW or PoS: The Difference Between Mined and Non-Mined Crypto
The whole crypto world discusses how Ethereum will switch from Proof of Work to Proof of Stake now. This change can significantly affect the cryptocurrency market. What are the positive and negative sides of PoW and PoS?
Cryptocurrencies can be divided into two types: those that can be mined (Bitcoin, Litecoin, Monero) and pre-mined ones (Ripple, Stellar, Cardano, EOS, NEO).

What is the big difference?

Although they differ in the method of generation, the basis of both types of crypto is the same: verification. Every transaction processed by the network must be verified by someone to ensure that virtual money has not been spent twice. Here we are talking about the difference in the verification process. Transaction groups are combined into a block; after verification, the block joins other previously confirmed blocks, and create a chain of transactions, or blockchain.

PoW: Mined Crypto

Mining is a process in which individuals, groups, or companies solve complex mathematical equations to verify transaction blocks using powerful computers. These math problems are part of the encryption process that protects transactions from cybercriminals and third party access.
The first who solves the problem and signs a block of transactions receives a reward. The miner, who confirmed the block of transactions e.g. in the Bitcoin network, receives a reward in BTC.

Disadvantages of Mined Crypto

  • Mining can be very expensive due to the large amounts of electricity consumed. In mined crypto with less capitalization, competition is usually lower than in BTC.
  • BTC mining requires special ASIC chips, that are combined into huge farms. Electricity is one of the main expenses for these projects. That is why China, where electricity is relatively cheap, has become a home to four of the five largest Bitcoin mining companies in the world.
  • Mining farms have to spend significant money funds on new equipment, which becomes out of date very fast.
  • Large projects need additional cooling, as servers and graphics cards heat up to high temperatures during operations.
  • The Proof-of-Work model is potentially vulnerable to a 51% attack (when a group of people with 51% of the computing power gains control of the network and its participants). For popular cryptocurrencies such as Bitcoin (BTC), Litecoin (LTC), and Monero (XMR) this is not a problem due to their large capitalization. However, minor cryptocurrencies with long block processing times and low daily volumes are risking a lot.

PoS: Non-Mined Crypto

At the other end of the spectrum are pre-mined cryptocurrencies such as Ripple (XRP), Stellar, Cardano, EOS, and NEO.
In the PoS model, super-powered computers are not needed, and participants do not compete for the right to sign the next block. Thus, the costs of this approach are significantly lower. Transaction verification is carried out by cryptocurrency owners. The more cryptocurrencies you have, the longer you own it, the higher the probability that you will be selected to check the transaction block.
Certain mechanisms are built into the system that prevents the dominance of large cryptocurrency holders over the verification process. There are many random ways to select owners who get the right to sign a transaction block. This ensures that small holders have a chance to participate in the process.

Disadvantages of Non-Mined Crypto

Despite the fact that the costs of the Proof-of-Stake method are lower, PoS has its drawbacks.
  • Such cryptocurrencies are not threatened by an attack of 51%, however, another trouble replaces it — a person who posses 51% of all tokens in circulation can gain control of the network and its participants. Of course, in the case of cryptocurrencies with high capitalization, the possibility of this scenario is low, but small partners may suffer from this vulnerability.
  • The Proof-of-Stake model also gives major owners additional votes in determining the future development of the network. Most NEO tokens) belong to several founders, for instance. This helps increase transaction speed and reduces consensus-building time, but also makes cryptocurrency too centralized. In other words, in the PoS model, large players gain significant power, which is theoretically impossible with the PoW model.

Which method is better?

Both methods have their pros and cons. Nevertheless, sooner or later, some of the largest mined currencies (e.g. BTC) will reach their token limit. At this point, they will have to switch to Proof-of-Stake. Since it significantly reduces power consumption and doesn't require powerful computers, gradually all crypto including BTC will switch to a non-mined model just like Ether did.

A Brief History of BitCoin

A Brief History of BitCoin


What is Bitcoin? | How It Work?

A Brief History of BitCoin

The virtual currency was intended to develop peer-to-peer transactions; it doesn’t need a go-between, the exchange of private information, or transaction fees.

What is Bitcoin?

Bitcoin is virtual money or cryptocurrency, that’s measured by a decentralized network of operators and isn’t straight subject to the impulses of central banking decisions or national governments. There are hundreds of cryptocurrencies in lively use today, Bitcoin is through far the most general and widely used – the nearby cryptocurrency equal to traditional, state-minted coins.

How Bitcoin Works

Bitcoin is a cryptocurrency since it’s supported by source code that customs highly composite procedures to prevent illegal duplication or creation of Bitcoin elements. The code’s fundamental principles, known as cryptography, are based on innovative scientific and computer engineering values. It’s practically impossible to stop Bitcoin’s source code and operate the currency’s supply.
Though it was headed by other virtual coins, Bitcoin is identified as the first modern cryptocurrency. That’s since Bitcoin is the initial to blend some key structures shared by most after created cryptocurrencies.

User Anonymity

Intense privacy safeties are seared into Bitcoin’s source code. The method is intended to openly record Bitcoin dealings and other related data without revealing the individuality of the groups involved. As a substitute, Bitcoin users are recognized by public keys or numerical codes that find them to additional users, and occasionally pseudonymous handles or usernames.

Bitcoin Exchanges

Bitcoin exchanges permit users to change Bitcoin parts for authorization currencies, such as the U.S. dollar and euro, at flexible exchange charges. Many Bitcoin relations also exchange Bitcoin components for other cryptocurrencies, with less popular substitutes that can’t straight be replaced for fiat coins. Most Bitcoin exchanges take a cut, naturally less than 1%, of each deal’s value.
Bitcoin exchanges certify that the Bitcoin market leftovers liquid, set their value qualified to traditional money – and allowing pouches to profit from the assumption on variations in that value.

BlockChain

Bitcoin’s blockchain is dynamic to its function. The blockchain is a public, spread record of all prior Bitcoin communications, which are kept in collections known as blocks. Each node of Bitcoin’s network – the server farms and positions, run by individuals or sets known as miners, whose hard work to produce new Bitcoin elements product in the recording and verification of Bitcoin dealings, and the episodic creation of new blocks – holds an identical record of Bitcoin’s blockchain.
Private Keys
Every Bitcoin handler has at smallest one private key, which is an entire number between 1 and 78 numbers in length. Separate users can have many unnamed handles, each with its private key. Private keys approve their owners’ characters and permit them to occupy or receive Bitcoin. Without them, handlers can’t whole transactions – they can’t access their properties until they improve the matching key. When a key is misplaced for good, the matching holdings change into a sort of everlasting limbo and can’t be improved.

Wallets

Real Bitcoin units are kept in “wallets” – secure cloud storing locations with superior information approving their owners (Bitcoin users) as the protectors of the Bitcoin units controlled within. However wallets like Coinbase, in theory, defend against the stealing of Bitcoin elements that aren’t currently being used, they’re exposed to hacking – mainly public wallets used by Bitcoin connections, online marketplaces, and specific websites that occur exclusively to store Bitcoin wallets known as “wallet services.”
Miners
Miners play an important role in the Bitcoin environment. As guards of the blockchain, they save the entire Bitcoin community truthful and indirectly provide the currency’s value. Miners are entities or cooperative governments with access to influential computers, often kept at remote, secretly owned “farms.” They do incredibly complex scientific tasks to new Bitcoin, which they then keep or change for fiat currency.

Modes of Bitcoin

  • Theft Private Keys.
  • Misusing Wallet Vulnerabilities
  • Functioning Fraudulent Exchanges and Savings Funds.
  • Attacking Authentic Exchanges Directly.
  • Aggressive Dark Web Marketplaces.

How to Get Bitcoin

There are three key ways people get Bitcoins.
  • You can purchase Bitcoins using ‘real’ money.
  • You can retail things and let persons pay with Bitcoins.
  • Developed using a computer.

Advantages of Using Bitcoin

  • Better Fluidity Comparative to Other currencies
  • Increasing the payment method
  • Worldwide Transactions Easier Than Even Currencies
  • Usually Lower Transaction Charges
  • Secrecy and Privacy Relative to Old Currencies
  • Individuality from Politically aware Agents and Creators
  • In-built Shortage

Disadvantages of Using Bitcoin

  • Exposure to Bitcoin-specific Tricks and Fraud
  • Black Market Motion May Damage Repute and Usefulness
  • Vulnerable to High Price Instability
  • No Chargebacks or Repayments
  • Possible to Be Replaced by Greater Cryptocurrency
  • Environmental Ills of Bitcoin Mining

Balance of Power - An Idea for a New Expansion to Civilization VI

CIVILIZATION VI - BALANCE OF POWER
New paths to victory and new dangers are in the game from the very first turn to the very last! The way the game itself begins is altered, and each civ plays more differently than ever with each leader having a unique set of buildings and different ways to pursue victory from turn one. Each leader is faced with new dangers, vicious Warlords have risen up to lead the warring barbarian clans to plunder your empire, and Plagues wait to spread in crowded and mismanaged cities!
Those who master a remade economic system featuring Corporations and World Market can conquer the world with the almighty dollar with Financial Victory!
New Civs
Pacal - Maya
Hammurabi - Babylon
Tamerlane - Timurids
Sitting Bull - Lakota
Henry the Navigator - Portugal
Vercingetorix - the Gauls
Nelson Mandela - South Africa
Leader Traits - Every Leader Upgraded!
  • All Leaders now have a new property. Each leader has Traits (ie; Mansa Musa is Financial and Charismatic, Gandhi is Spiritual and Industrious) which provide minor bonuses that guide towards one type of victory or the other. When a new Era begins, you get to choose which trait you want to focus on upgrading and select from one path or the other.
  • The base traits give a slight bonus and also change what buildings may be built in a city when first built. These buildings act like the Monument, providing Loyalty and a bonus at full loyalty, giving different bonuses based on the Trait.
  • Further tiers of traits give additional bonuses and unlock more special buildings for the City Center, with the final tier unlocking a special Wonder.
More Barbaric Barbarians!
Beasts
  • At the very start of the game, Barbarians may only spawn beasts and will not form Encampments until all civs have researched Code of Laws. In the very first turns, aggressive Beasts such as Bears, Lions, and Wolves will stalk around the unexplored wild in large numbers. Beasts ignore any movement penalties and hunt down civilians left unprotected. Beasts will promote themselves for each era they remain without getting killed, making exploration treacherous later on.
Warlords
  • Barbarians are now split into factions led by independent AI personalities called Warlords that are far more vicious than barbarians in vanilla. A barbarian camp in a forest tile, for example, is controlled by Boudica who prefers to build her unique unit the Pictish Warrior from her camp. One on a plains tile is controlled by Attila whose unique unit is a Hunnic Horseback Raider.
  • Warlords are at constant war with everyone else in the game and will only build military units. They are removed from the game if all encampments or cities they control are destroyed. Whenever a player kills a barbarian unit or loses a unit to barbarians, or when a barbarian scout spots their cities and sounds the horn for other barbarians, they have the opportunity to negotiate with the Warlord. For example one may bribe a Warlord to attack a rival civ instead of them.
Warlord-controlled Cities
  • Warlords that have not yet been removed from the game will attempt to establish themselves as governor of city states that have no Suzerain or Diplomat governor, transforming it into a free city. They instantly establish themselves in free cities near territory they control and cities conquered by barbarian hordes.
  • Unlike player controlled governors, Warlords may establish themselves in an unlimited number of cities, and gain a title whenever they take over a new city unlocking a new unique unit. Any player can establish trade routes to Warlord cities.
  • Removing a Warlord from the game allows the player that does so to build their unique units.
  • Special World Congress proposals can be triggered to allow Warlords to have a vote in World Congress if they are controlling cities.
A new way to win!
  • Financial Victory is unlocked. Unify all nations under the almighty dollar by dominating the World Market!
  • To win the Financial Victory, you must build the World Bank. This late game wonder may only be placed in a city that houses a Corporation Headquarters and may only be constructed by a civilization whose Currency is the preferred Currency of foreign trade in a majority of civlizations.
Currencies
  • Players can now issue their own currency upon learning the Foreign Trade civic. Custom Currencies allow you to change the value of your Gold by backing it on another resource such as your supply of Stone/Oil or a feature of your cities like Loyalty. You can opt to change your currency's form (giant rocks, paper bills, bitcoin etc.) to change its value in certain methods of trade and artificially inflate or deflate it. You can also choose to erase any customization by resetting your Currency to the Gold Standard. This can give you an edge in diplomacy trades against weaker civilizations and leverage the bonuses of Trade Routes in your favor.
  • Your currency is traded in lieu of gold once it is created. A civilization trading with you will give you their currency in exchange for yours. Currencies have different rates of exchanged based on their value. If foregin trade begins to outpace your own ability to generate gold, you may end up in a situation where another civ's Currency is the majority of gold in your coffers, making it the preferred Currency of foreign trade. If this is the case, you will tap into that before your own money in trades with other civs, denying you the Financial Victory!
  • Should a civilization be eliminated by being fully conquered, their Currency will remain and be traded for, but its value will be reset to the Gold Standard, which can drastically change the economies of civs they interacted with.
World Market
  • Gain access to the World Market after the Banking technology is learned. All Resources have a value in the World Market based on how many are being improved. This effects their values and similarly the world currencies are measured against each other in a similar way.
  • It is a virtual stock market where each resource being worked is its own stock, and money can be invested into speculation about whether those stocks may change in value.
  • The civ that has more than 50% of the global supply of a resource gains a Monopoly on it, giving tiles with those resources extra bonuses for that civ.
Corporations
  • Corporations can be founded after the Economics technology is researched. Once a civ has a Monopoly on a resource, it can build a Corporate HQ in the city center corresponding to that resource. There are also Corporations that can be only be founded by late game Great Merchants. HQs, Offices, and Franchises give gold and production.
  • Corporations are independent AIs that will periodically spawn special builders from Corporate buildings to use their corresponding resource to make products for the resource owner.
  • These products have useful bonuses when traded, and citizens of civs that do not have them will demand them. Corporations working resources alters their value in the World Market, as do the effects of foreign demand for products.
  • Once you found a corporation, you can build Corporate Offices in other cities. If a city with a Corporate Office connects a trade route to a foreign city that does not already have a Corporate Franchise in it, a Corporate Franchise is created. Each Office and Franchise helps spread your Corporation's influence and increase the bonuses from hosting them.
  • Corporation AIs give quests in the way city states do and will speculate on resources they want in the World Market and may be bet upon or against like with resources and currencies.
  • When a city that has constructed a Corporation Headquarters is acquired or destroyed through any means by another civilization, that Corporation is immediately destroyed. All Offices and Franchises around the world are immediately closed, and the founding Civilization immediately loses all benefits from that Corporation.
  • A destroyed Corporation immediately becomes available to be founded again by any civilization in the world. There is no restriction in the number of times a Corporation may be established in a game.
History comes alive!
  • As certain tiles are randomly hit with Natural Disasters, Districts and Wonders are rarely effected by Events that force the player to make choices which have unique and permanent effects on the wider world.
Player Events
  • Your Capital City has Player Events, rare occurrences that temporarily sway your civ's government, such as the sighting of a comet in the sky requiring the player to decide how to interpret such an omen, or the rising of a revolutionary army within the capital forcing the player to address their concerns or get ready to fight.
  • Player events may also be decided by the state of diplomacy such as your people clamoring for war after being your civ is wronged by another, or suffering from war weariness in the midst of a prolonged conflict.
Local Events
  • Districts may be effected by more Local Events that change the way the city grows based on your choices.
Wonder Quests
  • Certain Wonders have special quests attached to them that occur in multiple parts and specially upgrade the target Wonder based on your choices once all parts are complete.
Plauges!
  • A new form of Natural Disaster has arrived to lay waste to careless leaders that refuse to protect their people, they are called plagues, and will temporarily reduce Loyalty in afflicted cities with a chance to reduce population each turn. Later on, nearby tiles will have their yields negated.
How they work
  • Plagues function mostly like the Black Death scenario, but to begin affecting cities requires that a city have low housing or amenities for too many turns. Plagues begin when cities first become short on housing or amenities for more than a few turns.
  • Players are given warning that plagues may begin to spread when enough citizens become unhealthy from having too little housing or amenties.
  • Spies may trigger plagues by sabotaging Medical Districts. Special bio-weapons can be generated, a new variety of nuclear warhead that start uncurable plagues with extremely high chance to reduce population each turn.
Medical Pavillions
  • Special districts that may be built and serve the same function as the Walled Quarter in the Black Death scenario. The upgrade buildings in Medical Pavilions are required to build later game and more powerful versions of the special plague-centric civilians in the scenario.
  • Medical Pavilions help keep your citizens healthy and bring out their higher potential, making specialists more powerful.
Strains and Cures
  • Plagues come in many strains based on the Era of the game. Earlier plagues do not spread to other cities, eventually clearing out on their own. Later on, they become more virulent and begin to gain new attributes such as negating tiles near cities or spreading via trade routes. Very late game plagues even have a chance to bypass the beneficial effects of Medical District buildings.
  • Once the World Congress is unlocked, emergencies can be triggered to send aid to plague-stricken cities and even for the world to join in an effort to cure the different strains of plagues to prevent them from ever arising again.

Bitcoin (BTC)A Peer-to-Peer Electronic Cash System.

Bitcoin (BTC)A Peer-to-Peer Electronic Cash System.
  • Bitcoin (BTC) is a peer-to-peer cryptocurrency that aims to function as a means of exchange that is independent of any central authority. BTC can be transferred electronically in a secure, verifiable, and immutable way.
  • Launched in 2009, BTC is the first virtual currency to solve the double-spending issue by timestamping transactions before broadcasting them to all of the nodes in the Bitcoin network. The Bitcoin Protocol offered a solution to the Byzantine Generals’ Problem with a blockchain network structure, a notion first created by Stuart Haber and W. Scott Stornetta in 1991.
  • Bitcoin’s whitepaper was published pseudonymously in 2008 by an individual, or a group, with the pseudonym “Satoshi Nakamoto”, whose underlying identity has still not been verified.
  • The Bitcoin protocol uses an SHA-256d-based Proof-of-Work (PoW) algorithm to reach network consensus. Its network has a target block time of 10 minutes and a maximum supply of 21 million tokens, with a decaying token emission rate. To prevent fluctuation of the block time, the network’s block difficulty is re-adjusted through an algorithm based on the past 2016 block times.
  • With a block size limit capped at 1 megabyte, the Bitcoin Protocol has supported both the Lightning Network, a second-layer infrastructure for payment channels, and Segregated Witness, a soft-fork to increase the number of transactions on a block, as solutions to network scalability.

1. What is Bitcoin (BTC)?

  • Bitcoin is a peer-to-peer cryptocurrency that aims to function as a means of exchange and is independent of any central authority. Bitcoins are transferred electronically in a secure, verifiable, and immutable way.
  • Network validators, whom are often referred to as miners, participate in the SHA-256d-based Proof-of-Work consensus mechanism to determine the next global state of the blockchain.
  • The Bitcoin protocol has a target block time of 10 minutes, and a maximum supply of 21 million tokens. The only way new bitcoins can be produced is when a block producer generates a new valid block.
  • The protocol has a token emission rate that halves every 210,000 blocks, or approximately every 4 years.
  • Unlike public blockchain infrastructures supporting the development of decentralized applications (Ethereum), the Bitcoin protocol is primarily used only for payments, and has only very limited support for smart contract-like functionalities (Bitcoin “Script” is mostly used to create certain conditions before bitcoins are used to be spent).

2. Bitcoin’s core features

Unspent Transaction Output (UTXO) model

A UTXO transaction works like cash payment between two parties: Alice gives money to Bob and receives change (i.e., unspent amount). In comparison, blockchains like Ethereum rely on the account model.

Nakamoto consensus

In the Bitcoin network, anyone can join the network and become a bookkeeping service provider i.e., a validator. All validators are allowed in the race to become the block producer for the next block, yet only the first to complete a computationally heavy task will win. This feature is called Proof of Work (PoW).
The probability of any single validator to finish the task first is equal to the percentage of the total network computation power, or hash power, the validator has. For instance, a validator with 5% of the total network computation power will have a 5% chance of completing the task first, and therefore becoming the next block producer.
Since anyone can join the race, competition is prone to increase. In the early days, Bitcoin mining was mostly done by personal computer CPUs.
As of today, Bitcoin validators, or miners, have opted for dedicated and more powerful devices such as machines based on Application-Specific Integrated Circuit (“ASIC”).
Proof of Work secures the network as block producers must have spent resources external to the network (i.e., money to pay electricity), and can provide proof to other participants that they did so.
With various miners competing for block rewards, it becomes difficult for one single malicious party to gain network majority (defined as more than 51% of the network’s hash power in the Nakamoto consensus mechanism). The ability to rearrange transactions via 51% attacks indicates another feature of the Nakamoto consensus: the finality of transactions is only probabilistic.
Once a block is produced, it is then propagated by the block producer to all other validators to check on the validity of all transactions in that block. The block producer will receive rewards in the network’s native currency (i.e., bitcoin) as all validators approve the block and update their ledgers.

The blockchain

Block production

The Bitcoin protocol utilizes the Merkle tree data structure in order to organize hashes of numerous individual transactions into each block. This concept is named after Ralph Merkle, who patented it in 1979.
With the use of a Merkle tree, though each block might contain thousands of transactions, it will have the ability to combine all of their hashes and condense them into one, allowing efficient and secure verification of this group of transactions. This single hash called is a Merkle root, which is stored in the Block Header of a block. The Block Header also stores other meta information of a block, such as a hash of the previous Block Header, which enables blocks to be associated in a chain-like structure (hence the name “blockchain”).
An illustration of block production in the Bitcoin Protocol is demonstrated below.

https://preview.redd.it/m6texxicf3151.png?width=1591&format=png&auto=webp&s=f4253304912ed8370948b9c524e08fef28f1c78d

Block time and mining difficulty

Block time is the period required to create the next block in a network. As mentioned above, the node who solves the computationally intensive task will be allowed to produce the next block. Therefore, block time is directly correlated to the amount of time it takes for a node to find a solution to the task. The Bitcoin protocol sets a target block time of 10 minutes, and attempts to achieve this by introducing a variable named mining difficulty.
Mining difficulty refers to how difficult it is for the node to solve the computationally intensive task. If the network sets a high difficulty for the task, while miners have low computational power, which is often referred to as “hashrate”, it would statistically take longer for the nodes to get an answer for the task. If the difficulty is low, but miners have rather strong computational power, statistically, some nodes will be able to solve the task quickly.
Therefore, the 10 minute target block time is achieved by constantly and automatically adjusting the mining difficulty according to how much computational power there is amongst the nodes. The average block time of the network is evaluated after a certain number of blocks, and if it is greater than the expected block time, the difficulty level will decrease; if it is less than the expected block time, the difficulty level will increase.

What are orphan blocks?

In a PoW blockchain network, if the block time is too low, it would increase the likelihood of nodes producingorphan blocks, for which they would receive no reward. Orphan blocks are produced by nodes who solved the task but did not broadcast their results to the whole network the quickest due to network latency.
It takes time for a message to travel through a network, and it is entirely possible for 2 nodes to complete the task and start to broadcast their results to the network at roughly the same time, while one’s messages are received by all other nodes earlier as the node has low latency.
Imagine there is a network latency of 1 minute and a target block time of 2 minutes. A node could solve the task in around 1 minute but his message would take 1 minute to reach the rest of the nodes that are still working on the solution. While his message travels through the network, all the work done by all other nodes during that 1 minute, even if these nodes also complete the task, would go to waste. In this case, 50% of the computational power contributed to the network is wasted.
The percentage of wasted computational power would proportionally decrease if the mining difficulty were higher, as it would statistically take longer for miners to complete the task. In other words, if the mining difficulty, and therefore targeted block time is low, miners with powerful and often centralized mining facilities would get a higher chance of becoming the block producer, while the participation of weaker miners would become in vain. This introduces possible centralization and weakens the overall security of the network.
However, given a limited amount of transactions that can be stored in a block, making the block time too longwould decrease the number of transactions the network can process per second, negatively affecting network scalability.

3. Bitcoin’s additional features

Segregated Witness (SegWit)

Segregated Witness, often abbreviated as SegWit, is a protocol upgrade proposal that went live in August 2017.
SegWit separates witness signatures from transaction-related data. Witness signatures in legacy Bitcoin blocks often take more than 50% of the block size. By removing witness signatures from the transaction block, this protocol upgrade effectively increases the number of transactions that can be stored in a single block, enabling the network to handle more transactions per second. As a result, SegWit increases the scalability of Nakamoto consensus-based blockchain networks like Bitcoin and Litecoin.
SegWit also makes transactions cheaper. Since transaction fees are derived from how much data is being processed by the block producer, the more transactions that can be stored in a 1MB block, the cheaper individual transactions become.
https://preview.redd.it/depya70mf3151.png?width=1601&format=png&auto=webp&s=a6499aa2131fbf347f8ffd812930b2f7d66be48e
The legacy Bitcoin block has a block size limit of 1 megabyte, and any change on the block size would require a network hard-fork. On August 1st 2017, the first hard-fork occurred, leading to the creation of Bitcoin Cash (“BCH”), which introduced an 8 megabyte block size limit.
Conversely, Segregated Witness was a soft-fork: it never changed the transaction block size limit of the network. Instead, it added an extended block with an upper limit of 3 megabytes, which contains solely witness signatures, to the 1 megabyte block that contains only transaction data. This new block type can be processed even by nodes that have not completed the SegWit protocol upgrade.
Furthermore, the separation of witness signatures from transaction data solves the malleability issue with the original Bitcoin protocol. Without Segregated Witness, these signatures could be altered before the block is validated by miners. Indeed, alterations can be done in such a way that if the system does a mathematical check, the signature would still be valid. However, since the values in the signature are changed, the two signatures would create vastly different hash values.
For instance, if a witness signature states “6,” it has a mathematical value of 6, and would create a hash value of 12345. However, if the witness signature were changed to “06”, it would maintain a mathematical value of 6 while creating a (faulty) hash value of 67890.
Since the mathematical values are the same, the altered signature remains a valid signature. This would create a bookkeeping issue, as transactions in Nakamoto consensus-based blockchain networks are documented with these hash values, or transaction IDs. Effectively, one can alter a transaction ID to a new one, and the new ID can still be valid.
This can create many issues, as illustrated in the below example:
  1. Alice sends Bob 1 BTC, and Bob sends Merchant Carol this 1 BTC for some goods.
  2. Bob sends Carols this 1 BTC, while the transaction from Alice to Bob is not yet validated. Carol sees this incoming transaction of 1 BTC to him, and immediately ships goods to B.
  3. At the moment, the transaction from Alice to Bob is still not confirmed by the network, and Bob can change the witness signature, therefore changing this transaction ID from 12345 to 67890.
  4. Now Carol will not receive his 1 BTC, as the network looks for transaction 12345 to ensure that Bob’s wallet balance is valid.
  5. As this particular transaction ID changed from 12345 to 67890, the transaction from Bob to Carol will fail, and Bob will get his goods while still holding his BTC.
With the Segregated Witness upgrade, such instances can not happen again. This is because the witness signatures are moved outside of the transaction block into an extended block, and altering the witness signature won’t affect the transaction ID.
Since the transaction malleability issue is fixed, Segregated Witness also enables the proper functioning of second-layer scalability solutions on the Bitcoin protocol, such as the Lightning Network.

Lightning Network

Lightning Network is a second-layer micropayment solution for scalability.
Specifically, Lightning Network aims to enable near-instant and low-cost payments between merchants and customers that wish to use bitcoins.
Lightning Network was conceptualized in a whitepaper by Joseph Poon and Thaddeus Dryja in 2015. Since then, it has been implemented by multiple companies. The most prominent of them include Blockstream, Lightning Labs, and ACINQ.
A list of curated resources relevant to Lightning Network can be found here.
In the Lightning Network, if a customer wishes to transact with a merchant, both of them need to open a payment channel, which operates off the Bitcoin blockchain (i.e., off-chain vs. on-chain). None of the transaction details from this payment channel are recorded on the blockchain, and only when the channel is closed will the end result of both party’s wallet balances be updated to the blockchain. The blockchain only serves as a settlement layer for Lightning transactions.
Since all transactions done via the payment channel are conducted independently of the Nakamoto consensus, both parties involved in transactions do not need to wait for network confirmation on transactions. Instead, transacting parties would pay transaction fees to Bitcoin miners only when they decide to close the channel.
https://preview.redd.it/cy56icarf3151.png?width=1601&format=png&auto=webp&s=b239a63c6a87ec6cc1b18ce2cbd0355f8831c3a8
One limitation to the Lightning Network is that it requires a person to be online to receive transactions attributing towards him. Another limitation in user experience could be that one needs to lock up some funds every time he wishes to open a payment channel, and is only able to use that fund within the channel.
However, this does not mean he needs to create new channels every time he wishes to transact with a different person on the Lightning Network. If Alice wants to send money to Carol, but they do not have a payment channel open, they can ask Bob, who has payment channels open to both Alice and Carol, to help make that transaction. Alice will be able to send funds to Bob, and Bob to Carol. Hence, the number of “payment hubs” (i.e., Bob in the previous example) correlates with both the convenience and the usability of the Lightning Network for real-world applications.

Schnorr Signature upgrade proposal

Elliptic Curve Digital Signature Algorithm (“ECDSA”) signatures are used to sign transactions on the Bitcoin blockchain.
https://preview.redd.it/hjeqe4l7g3151.png?width=1601&format=png&auto=webp&s=8014fb08fe62ac4d91645499bc0c7e1c04c5d7c4
However, many developers now advocate for replacing ECDSA with Schnorr Signature. Once Schnorr Signatures are implemented, multiple parties can collaborate in producing a signature that is valid for the sum of their public keys.
This would primarily be beneficial for network scalability. When multiple addresses were to conduct transactions to a single address, each transaction would require their own signature. With Schnorr Signature, all these signatures would be combined into one. As a result, the network would be able to store more transactions in a single block.
https://preview.redd.it/axg3wayag3151.png?width=1601&format=png&auto=webp&s=93d958fa6b0e623caa82ca71fe457b4daa88c71e
The reduced size in signatures implies a reduced cost on transaction fees. The group of senders can split the transaction fees for that one group signature, instead of paying for one personal signature individually.
Schnorr Signature also improves network privacy and token fungibility. A third-party observer will not be able to detect if a user is sending a multi-signature transaction, since the signature will be in the same format as a single-signature transaction.

4. Economics and supply distribution

The Bitcoin protocol utilizes the Nakamoto consensus, and nodes validate blocks via Proof-of-Work mining. The bitcoin token was not pre-mined, and has a maximum supply of 21 million. The initial reward for a block was 50 BTC per block. Block mining rewards halve every 210,000 blocks. Since the average time for block production on the blockchain is 10 minutes, it implies that the block reward halving events will approximately take place every 4 years.
As of May 12th 2020, the block mining rewards are 6.25 BTC per block. Transaction fees also represent a minor revenue stream for miners.

What are the top #10 crypto coins everyone should know?

Top 10 Crypto Coins you might not (yet) have heard about (but are important to know)

Ever heard of Bitcoin, Bitcoin Cash and maybe Ether? That‘s a rather rhetorical question as you have somehow found your way to this article. Knowledge about the existence of crypto currencies, mostly about bitcoin is part of the technology mainstream. About 9 out of 10 Americans have knowledge about bitcoin as latest enquiries show. That raises two interesting questions:

1) How far along the way is the mass adoption of crypto currencies worldwide?

Everybody knowing about something should mean also everybody using it, correct? For bitcoin (and also other crytos) that does not seem to be true. There are around 35 million bitcoin wallets worldwide and around 50 million bitcoin users. That is not even 1% of our global population. Bitcoin and other cryptos are still not part of everyday life for the majority of humanity. If this feels different for you you might be living in a bubble. The adoption however is an important measure when it comes to anticipating a future price increase in the value of bitcoin. Which leads us to the second interesting question:

2) What are the crypto coins that are less well known but still show potential

Besides bitcoin there are other crypto currencies, also called alternative coins or altcoins. Bitcoin is the dominant crypto coin capturing a overall market cap of around 70% – 75%. This means that from all investments done into cryptos around 70% – 75% are placed into bitcoins. Whenever there is a bull rally in the markets, altcoins tend to outperform the market leader bitcoin. Imagine this effect similarly to the S&P 500 Index encompassing the top 500 US companies. When the S&P 500 Index value increases 1% this can mean that one index constituent actually increased by 30% in value pushing the overall index value.
Here a list of interesting altcoins you might want to follow more closely in the future (not connected to any type of investment advice whatsoever):
Waves (WAVES)
Waves is the coin of the Waves platform, a blockchain platform for custom tokens. Custom tokens target a mass market and allow users with limited technical knowledge to build virtually any type of use case based on the token. Waves USP is user friendliness as well that reflects in their lite wallet as well.
Vertcoin (VTC)
Vertcoin calls itself the peoples coin which refers to Vertcoin‘s goal to be so easy that everyday people with desktop computers can mine Vertcoin. Vertcoin, on the market since 2014, aimed to equal out disadvantages of bitcoin by for example applying a proof-of-work mechanism with Lyra2REv3 as underlying hash function.
PotCoin (POT)
PotCoin aims to become the number one currency for the constantly growing cannabis industry. The initial idea was to have a payment method in place that would facilitate transactions in the legal marijuana industry – a industry still underserved by the classical banking sector. In 2015 PotCoin moved to a proof-of-stake mechanism.
Monero (XMR)
Monero‘s focus is anonymity. Unlike for example bitcoin, money in- and outflows are not publicly visible on Monero‘s blockchain. Transaction mining is also not possible as Monero is mixing transaction in such a manner that is basically impossible to reverse engineer useful information out of the data.
Komodo (KMD)
Komodo, in its core based on bitcoins blockchain, was launched to equal out the many disadvantages of Bitcoin. The ambition of Komodo reflects in the vast amount of features and coming features this coin is equipped with. Komodo started by allowing for real anonymity in transactions.
Dogecoin (DOGE)
Dogecoin started as a joke, as a parody to Bitcoin and its skyrocking success. In its core Dogecoin is similar to bitcoin or litecoin respectively. The biggest difference however is that (unlikes bitcoins 21 million coins limit) there is no limit for mining Dogecoins.
DigiByte (DGB)
If you feel that bitcoin is slow, insecure and bulky then DigiByte should be your coin of choice. It was created having mainly cybersecurity in mind. DigiByte is several times faster compared to Bitcoin and the coins have very favorable security features build in making it safer to use and creating use-cases in the IoT space for example.
Decred (DCR)
Decred is bringing grasroot democracy to the crypto world. With Bitcoin the complete power over the blockchain is in the hand of the miners. With Decred this power is split within the stakeholders (developers, miners and investors) by a transparent reward system. In addition to that Decred has many innovative features build in.
Dash (DASH)
Dash coin was designed with keeping an eye on user privacy. Transactions are not publicly accessible and mixed in a manner that it‘s impossible to reverse engineer. Dash became famous when they offered easy accessibility to their network for the inhabitants of Venezuela during their economic crisis.
BlackCoin (BLK)
BlackCoin was build with the focus to be fully working on the Proof-of-Stake principle, making it very fast in validating transactions. That not only makes it fun to use but is actually creating use-cases such as in e-commerce where a fast payment confirmation is critical.
Litecoin (LTC)
Litecoin was build as a competitor to Bitcoin and is one of the best known altcoins. Litecoin is fast in creating blocks (2,5 minutes) making validating transactions faster as well. Mining is distributed among the miners much better than bitcoin making centralisation much harder.
The featured coins here are subject to many risk factors including full or partial loss of value. The feature is not intended to serve as investment advice.

Are you among the winning early adopters?

All mentioned coins can be used to purchase anonymous domains and related anonymous webservices on our website BitDomain.BIZ. The reason for that is that early adoption has proven to be a winning strategy in the crypto space. That is why at BitDomain.BIZ we are constantly accepting new and promising crypto coins to purchase our anonymous digital publishing services.

Crypto-Currency: A Guide to Common Tax Situations

STATUS: Majority of questions have been answered. If yours got missed, please feel free to post it again.
Introduction
All,
Based on the rapid increase in popularity and price of bitcoin and other crypto currencies (particularly over the past year), I expect that lots of people have questions about how crypto currency will impact their taxes. This thread attempts to address several common issues. I'm posting similar versions of it here, in several major crypto subs, and eventually in the weekly "tax help" threads personalfinance runs.
I'd like to thank the /personalfinance mod team and the /tax community for their help with this thread and especially for reading earlier versions and offering several valuable suggestions/corrections.
This thread is NOT an endorsement of crypto currency as an investing strategy. There is a time and a place to debate the appropriateness of crypto as part of a diversified portfolio - but that time is not now and that place is not here. If you are interested in the general consensus of this sub on investing, I would urge you to consult the wiki while keeping in mind the general flowchart outlining basic steps to get your finances in order.
Finally, please note that this thread attempts to provide information about your tax obligations as defined by United States law (and interpreted by the IRS under the direction of the Treasury Department). I understand that a certain portion of the crypto community tends to view crypto as "tax free" due to the (actual and perceived) difficulty for the IRS to "know" about the transactions involved. I will not discuss unlawfully concealing crypto gains here nor will I suggest illegal tax avoidance activities.
The Basics
This section is best for people that don't understand much about taxes. It covers some very basic tax principles. It also assumes that all you did during the year was buy/sell a single crypto currency.
Fundamentally, the IRS treats crypto not as money, but as an asset (investment). While there are a few specific "twists" when it comes to crypto, when in doubt replace the word "crypto" with the word "stock" and you will get a pretty good idea how you should report and pay tax on crypto.
The first thing you should know is that the majority of this discussion applies to the taxes you are currently working on (2017 taxes). The tax bill that just passed applies to 2018 taxes (with a few very tiny exceptions), which most people will file in early 2019.
In general, you don't have to report or pay taxes on crypto currency holdings until you "cash out" all or part of your holdings. For now, I'm going to assume that you cash out by selling them for USD; however, other forms of cashing out will be covered later.
When you sell crypto, you report the difference between your basis (purchase price) and proceeds (sale price) on Schedule D. Your purchase price is commonly referred to as your basis; while the two terms don't mean exactly the same thing, they are pretty close to one another (in particular, there are three two ways to calculate your basis - your average cost, a first-in, first-out method, and a "specific identification" method. See more about these here and here). EDIT - you may not use average cost method with crypto - see here. If you sell at a gain, this gain increases your tax liability; if you sell at a loss, this loss decreases your tax liability (in most cases). If you sell multiple times during the year, you report each transaction separately (bad news if you trade often) but get to lump all your gains/losses together when determining how the trades impact your income.
One important thing to remember is that there are two different types of gains/losses from investments - short term gains (if you held an asset for one year or less) and long term gains (over one year; i.e. one year and one day). Short term gains are taxed at your marginal income rate (basically, just like if you had earned that money at a job) while long term gains are taxed at lower rates.
For most people, long term capital gains are taxed at 15%. However, if you are in the 10% or 15% tax bracket, congrats - your gains (up to the maximum amount of "unused space" in your bracket) are tax free! If you are in the 25%, 28%, 33%, or 35% bracket, long term gains are taxed at 15%. If you are in the 39.6% bracket, long term gains are taxed at 20%. Additionally, there is an "extra" 3.8% tax that applies to gains for those above $200,000/$250,000 (single/married). The exact computation of this tax is a little complicated, but if you are close to the $200,000 level, just know that it exists.
Finally, you should know that I'm assuming that you should treat your crypto gains/losses as investment gains/losses. I'm sure some people will try and argue that they are really "day traders" of crypto and trade as a full time job. While this is possible, the vast majority of people don't qualify for this status and you should really think several times before deciding you want to try that approach on the IRS.
"Cashing Out" - Trading Crypto for Goods/Services
I realize that not everyone that "cashes out" of crypto does so by selling it for USD. In fact, I understand that some in the crypto community view the necessity of cashing out itself as a type of myth. In this section, I discuss what happens if you trade your crypto for basically anything that isn't cash (minor sidenote - see next section for a special discussion on trading crypto for crypto; i.e. buying altcoins with crypto).
The IRS views trading crypto for something of value as a type of bartering that must be included in income. From the IRS's perspective, it doesn't matter if you sold crypto for cash and bought a car with that cash or if you just traded crypto directly for the car - in both cases, the IRS views you as having sold your crypto. This approach isn't unique to crypto - it works the same way if you trade stock for something.
This means that if you do trade your crypto for "stuff", you have to report every exchange as a sale of your crypto and calculate the gain/loss on that sale, just as if you had sold the crypto for cash.
Finally, there is one important exception to this rule. If you give your crypto away to charity (one recognized by the IRS; like a 501(c)(3) organization), the IRS doesn't make you report/pay any capital gains on the transaction. Additionally, you still get to deduct the value of your donation on the date it was made. Now, from a "selfish" point of view, you will always end up with more money if you sell the crypto, pay the tax, and keep the rest. But, if you are going to make a donation anyway, especially a large one, giving crypto where you have a big unrealized/untaxed gain is a very efficient way of doing so.
"Alt Coins" - Buying Crypto with Crypto
The previous section discusses what happens when you trade crypto for stuff. However, one thing that surprises many people is that trading crypto for crypto is also a taxable event, just like trading crypto for a car. Whether you agree with this position or not, it makes a lot of sense once you realize that the IRS doesn't view crypto as money, but instead as an asset. So to the IRS, trading bitcoin for ripple isn't like trading dollars for euros, but it is instead like trading shares of Apple stock for shares of Tesla stock.
Practically, what this means is that if you trade one crypto for another crypto (say BTC for XRP just to illustrate the point), the IRS views you as doing the following:
  • Selling for cash the amount of BTC you actually traded for XRP.
  • Owing capital gains/losses on the BTC based on its selling price (the fair market value at the moment of the exchange) and your purchase price (basis).
  • Buying a new investment (XRP) with a cost basis equal to the amount the BTC was worth when you exchanged them.
This means that if you "time" your trade wrong and the value of XRP goes down after you make the exchange, you still owe tax on your BTC gain even though you subsequently lost money. The one good piece of news in this is that when/if you sell your XRP (or change it back to BTC), you will get a capital loss for the value that XRP dropped.
There is one final point worth discussing in this section - the so called "like kind exchange" rules (aka section 1031 exchange). At a high level, these rules say that you can "swap" property with someone else without having to pay taxes on the exchange as long as you get property in return that is "like kind". Typically, these rules are used in real estate transactions. However, they can also apply to other types of transactions as well.
While the idea is simple (and makes it sound like crypto for crypto should qualify), the exact rules/details of this exception are very fact specific. Most experts (including myself, but certainly not calling myself an expert) believe that a crypto for crypto swap is not a like kind exchange. The recently passed tax bill also explicitly clarifies this issue - starting in 2018, only real estate qualifies for like kind exchange treatment. So, basically, the vast majority of evidence suggests that you can't use this "loophole" for 2017; however, there is a small minority view/some small amount of belief that this treatment would work for 2017 taxes and it is worth noting that I'm unaware of any court cases directly testing this approach.
Dealing with "Forks"
Perhaps another unpleasant surprise for crypto holders is that "forks" to create a new crypto also very likely generate a taxable event. The IRS has long (since at least the 1960s) held that "found" money is a taxable event. This approach has been litigated in court and courts have consistently upheld this position; it even has its own cool nerdy tax name - the "treasure trove" doctrine.
Practically, what this means is that if you owned BTC and it "forked" to create BCH, then the fair market value of the BCH you received is considered a "treasure trove" that must be reported as income (ordinary income - no capital gain rates). This is true whether or not you sold your BCH; if you got BCH from a fork, that is a taxable event (note - I'll continue using BTC forking to BCH in this section as an example, but the logic applies to all forks).
While everything I've discussed up to this point is pretty clearly established tax law, forks are really where things get messy with taxes. Thus, the remainder of this section contains more speculation than elsewhere in this post - the truth is that while the idea is simple (fork = free money = taxable), the details are messy and other kinds of tax treatment might apply to forks.
One basic practical problem with forks is that the new currency doesn't necessarily start trading immediately. Thus, you may have received BCH before there was a clear price or market for it. Basically, you owe tax on the value of BCH when you received it, but it isn't completely clear what that value was. There are several ways you can handle this; I'll list them in order from most accurate to least accurate (but note that this is just my personal view and there is ongoing disagreement on this issue with little/no authoritative guidance).
  • Use a futures market to determine the value of the BCH - if reliable sources published realistic estimates of what BCH will trade for in the future once trading begins, use this estimate as the value of your BCH. Pros/cons - futures markets are, in theory, pretty accurate. However, if they are volatile/subject to manipulation, they may provide an incorrect estimate of the true value of BCH. It would suck to use the first futures value published only to have that value plummet shortly thereafter, leaving you to pay ordinary income tax but only have an unrealized capital loss.
  • Wait until an exchange starts trading BCH; use the actual ("spot" price) as the value. Pros/cons - spot prices certainly reflect what you could have sold BCH for; however, it is possible that the true value of the coin was highelower when you received it as compared to when it started trading on the exchange. Thus this method seems less accurate to me than a futures based approach, but it is still certainly fairly reasonable.
  • Assume that the value is $0. This is my least preferred option, but there is still a case to be made for it. If you receive something that you didn't want, can't access, can't sell, and might fail, does it have any value? I believe the answer is yes (maybe not value it perfectly, but value it somewhat accurately), but if you honestly think the answer is no, then the correct tax answer would be to report $0 in income from the fork. The IRS would be most likely to disagree with this approach, especially since it results in the least amount of income reported for the current year (and the most favorable rates going forward). Accordingly, if you go this route, make extra sure you understand what it entails.
Note, once you've decided what to report as taxable income, this amount also becomes your cost basis in the new crypto (BCH). Thus, when you ultimately sell your BCH (or trade it for something else as described above), you calculate your gain/loss based on what you included in taxable income from the fork.
Finally, there is one more approach to dealing with forks worth mentioning. A fork "feels" a lot like a dividend - because you held BTC, you get BCH. In a stock world, if I get a cash dividend because I own the stock, that money is not treated as a "treasure trove" and subject to ordinary income rates - in most cases, it is a qualified dividend and subject to capital gain rates; in some cases, some types of stock dividends are completely non taxable. This article discusses this idea in slightly more detail and generally concludes that forks should not be treated as a dividend. Still, I would note that I'm unaware of any court cases directly testing this theory.
Ultimately, this post is supposed to be practical, so let me make sure to leave you with two key thoughts about the taxation of forks. First, I believe that the majority of evidence suggests that forks should be treated as a "treasure trove" and reported as ordinary income based on their value at creation and that this is certainly the "safest" option. Second, out of everything discussed in this post, I also believe that the correct taxation of forks is the murkiest and most "up for debate" area. If you are interested in a more detailed discussion of forks, see this thread for a previous version of this post discussing it at even more length and the comments for a discussion of this with the tax community.
Mining Crypto
Successfully mining crypto coins is a taxable event. Depending on the amount of effort you put into mining, it is either considered a hobby or a self-employment (business) activity. The IRS provides the following list of questions to help decide the correct classification:
  • The manner in which the taxpayer carries on the activity.
  • The expertise of the taxpayer or his advisors.
  • The time and effort expended by the taxpayer in carrying on the activity.
  • Expectation that assets used in activity may appreciate in value.
  • The success of the taxpayer in carrying on other similar or dissimilar activities.
  • The taxpayer’s history of income or losses with respect to the activity.
  • The amount of occasional profits, if any, which are earned.
If this still sounds complicated, that's because the distinction is subject to some amount of interpretation. As a rule of thumb, randomly mining crypto on an old computer is probably a hobby; mining full time on a custom rig is probably a business.
In either event, you must include in income the fair market value of any coins you successfully mine. These are ordinary income and your basis in these coins is their fair market value on the date they were mined. If your mining is a hobby, they go on line 21 (other income) and any expenses directly associated with mining go on schedule A (miscellaneous subject to 2% of AGI limitation). If your mining is a business, income and expenses go on schedule C.
Both approaches have pros and cons - hobby income isn't subject to the 15.3% self-employment tax, only normal income tax, but you get fewer deductions against your income and the deductions you get are less valuable. Business income has more deductions available, but you have to pay payroll (self-employment) tax of about 15.3% in addition to normal income tax.
What if I didn't keep good records? Do I really have to report every transaction?
One nice thing about the IRS treating crypto as an asset is that we can look at how the IRS treats people that "day trade" stock and often don't keep great records/have lots of transactions. While you need to be as accurate as possible, it is ok to estimate a little bit if you don't have exact records (especially concerning your cost basis). You need to put in some effort (research historical prices, etc...) and be reasonable, but the IRS would much rather you do a little bit of reasonable estimation as opposed to just not reporting anything. Sure, they might decide to audit you/disagree with some specifics, but you earn yourself a lot of credit if you can show that you honestly did the best you reasonably could and are making efforts to improve going forward.
However, concerning reporting every transaction - yes, sorry, it is clear that you have to do this, even if you made hundreds or thousands of them. Stock traders have had to go through this for many decades, and there is absolutely no reason to believe that the IRS would accept anything less from the crypto community. If you have the records or have any reasonable way of obtaining records/estimating them, you must report every transaction.
What if I don't trust you?
Well, first let me say that I can't believe you made it all the way down here to this section. Thanks for giving me an honest hearing. I would strongly encourage you to go read other well-written, honest guides. I'll link to some I like (both more technical IRS type guides and more crypto community driven guides). While a certain portion of the crypto community seems to view one of the benefits of crypto as avoiding all government regulation (including taxes), I've been pleasantly surprised to find that many crypto forums contain well reasoned, accurate tax guides. While I may not agree with 100% of their conclusions, that likely reflects true uncertainty around tax law that is fundamentally complex rather than an attempt on either end to help individuals unlawfully avoid taxes.

ارز دیجیتال چیست ؟

در ابتدا بگذارید کمی دقیق‌تر راجع به خود واژه‌ی «ارز دیجیتال » صحبت کنیم. ارز دیجیتال ترجمه عبارت انگلیسی Digital Currency می‌باشد. Digital Currency نوعی از ارز است که به صورت دیجیتالی یا الکترونیکی وجود دارد. در واقع این نوع از ارز به فرم فیزیکی موجود نیست. از ارزهای دیجیتال (یا ارز دیجیتالی) با نام‌های پول دیجیتالی (digital money)، پول الکترونیکی (electronic money)، ارز الکترونیکی (electronic currency) یا وجه نقد سایبری (cyber cash) نیز یاد می‌شود.
ارزهای دیجیتال از مدت‌ها قبل وجود داشته‌اند و عمر زیادی دارند. علاوه بر این تنوع آن‌ها نیز بالا می‌باشد. از ارز های مجازی (virtual currencies) و ارزدیجیتال بانک مرکزی (central bank digital currency) می‌توان به عنوان مثال‌هایی از ارزهای دیجیتال یاد کرد. اما به تازگی نوع دیگری از ارز های دیجیتال نیز به وجود آمده. ارز هایی که تاثیرات بزرگی بر نقل و انتقالات پولی داشته است. نام این دسته‌ی جدید ارز های رمز پایه (Cryptocurrency) است.
در واقع ارز های رمزپایه خود یکی از انواع ارزهای دیجیتال هستند. اما در ایران زمانی که کسی می‌گوید ارزدیجیتال، احتمالا منظورش همان ارز های رمزپایه است. در این نوشته نیز هر گاه که از واژه‌ی «ارز دیجیتال» استفاده شد، منظور همان ارز های رمزپایه است.

ارزهای دیجیتال انوع مختلفی دارد. ارزهای مجازی، ارزدیجیتال بانک مرکزی و ارزهای رمز پایه سه نوع معروف آن‌ها می‌باشد. در نتیجه ارز های رمزپایه (cryptocurrency) مثل بیت کوین، ارز دیجیتال نیز هستند. اما همه‌ی ارزهای دیجیتال لزوما ارز رمزپایه نیستند. در ایران زمانی که گفته می‌شود ارزهای دیجیتال، معمولا منظور نوع معروف آن یعنی ارز های رمزپایه است.

ارز رمزپایه یا ارز دیجیتال

ارز رمزپایه (cryptocurrency) خود نوعی از ارزهای دیجیتالی (digital) یا ارز مجازی (virtual) است. امنیت این ارز با استفاده از تکنیک cryptography تضمین می‌شود (در واقع واژه‌ی cryptocurrency نیز از ترکیب واژه‌ی cryptography و currency به دست آمده است. cryptography به معنای رمزنگاری یا نهان‌نگاری می‌باشد. با استفاده از cryptography مشکل دو بار خرج کردن (double-spending) و انتقال پول‌های جعلی (counterfeit) حل می‌شود. این دو مشکل در ذات انواع دیگر پول‌های دیجیتال وجود دارد.
به ارز های رمزپایه، رمز ارز یا ارز های رمزنگاری شده نیز گفته می‌شود. بسیاری از ارزهای رمزنگاری شده شبکه های غیر متمرکزی (decentralized networks) هستند که مبتنی بر فناوری زنجیره بلوکی یا بلاکچین (blockchain) [یک دفتر کل توزیع شده که توسط مجموعه نابرابری از کامپیوترها تایید می‌شود] به وجود آمده است. از ویژگی‌های مهم رمزارزها این است که آنها توسط هیچ شخص، مرکز یا گروهی کنترل نمی‌شوند. از نظر نظری دخالت و دستکاری آن‌ها ممکن نیست.

ارز های دیجیتال در یک نگاه


  • ارزهای دیجیتال شکل جدیدی از دارایی‌های دیجیتال هستند که مبتنی بر شبکه‌ای غیرمترکز از تعداد زیادی کامپیوتر کار می‌کند. این ساختار غیر متمرکز به آن‌ها اجازه می‌دهد تا دولت‌ها یا مقامات مرکزی هیچ کنترلی بر آن‌ها نتوانند داشته باشند.
  • واژه «cryptocurrency» ریشه در «cryptography» و تکنیک‌های رمزگذاری دارد. این تکنیک‌ها برای تضمین امنیت شبکه استفاده میشود.
  • زنجیره‌های بلوکی یا Blockchain ها، که روشی برای اطمینان از یکپارچگی داده‌های مربوط به معاملات هستند، از اساسی‌ترین مؤلفه‌های ارزهای رمزپایه هستند.
  • بسیاری از کارشناسان معتقدند که Blockchain و فناوری‌های مرتبط با آن، بسیاری از صنایع از جمله صنعت مالی را دگرگون و مختل خواهد کرد.
  • نقدهای زیادی بر ارزهای رمزپایه وارد است. استفاده از آنها در فعالیت‌های غیرقانونی، نوسانات بالای ارزش ارزها و آسیب پذیری‌های زیرساخت‌های آن‌ها از جمله این نقدها است. با این حال، این ارزها همچنان بخاطر قابلیت انتقال آسان، تقسیم پذیری، مقاومت در برابر تورم و شفافیت مورد تحسین قرار گرفته‌اند.

ارز های دیجیتال چه انواعی دارد ؟

اولین ارز رمزپایه به وجود آمده بر پایه بلاکچین بیت کوین (Bitcoin) است. بیت کوین هنوز هم محبوب ترین و با ارزش‌ترین ارز دنیای ارزهای دیجیتال است. امروزه هزاران ارز رمزپایه دیگر با کارکردها و مشخصات گوناگون به وجود آمده است. برخی از این ارزها از بیت کوین ریشه گرفته‌اند و اصطلاحا یک کلون (clone) یا فورک (fork)) از آن هستند (clone در زیست‌شناسی به معنای تولید مثلا از راه شکفتن یا تقسیم سلولی است، fork نیز به معنای تقسیم چیزی به دو یا چند شاخه است). این در حالی است که بسیاری از ارزهای دیگر از ابتدا و بر روی شبکه‌ی خاص خودشان ایجاد شده‌اند.
بیت کوین در سال ۲۰۰۹ توسط فرد یا گروهی که با نام مستعار ساتوشی ناکاموتو (Satoshi Nakamoto) شناخته می‌شود به وجود آمد. در ماه نوامبر ۲۰۱۹، بیش از ۱۸ میلیون بیت کوین با ارزش کل بازار در حدود ۱۴۶ میلیارد دلار در گردش بوده است [۴].
برخی از ارزهای رمزپایه دیگر (معروف به آلتکوین altcoin) که در ادامه‌ی موفقیت بیت کوین ایجاد شده‌اند عبارتند از: لایت کوین(litecoin)، اتریوم (Ethereum)، ایاس (EOS) و کاردانو (Cardano). در حال حاضر، کل ارزش ارزهای دیجیتال موجود چیزی در حدود ۲۱۴ میلیارد دلار است. از این مقدار چیزی بیش از ۶۸٪ از کل این ارزش متعلق به بیت کوین است.

ملاحظات ویژه!

نکته اصلی در جذابیت و کارایی بیت کوین و سایر ارزهای دیجیتال، فناوری blockchain است. این فناوری یک دفتر کل آنلاین (تاریخچه) از کل معاملاتی است که تا کنون انجام گرفته است را نگه‌داری می‌کند. اینگونه ساختاری از داده‌ها ایجاد می‌شود که کاملا امن است و نه تنها با تک تک گره‌های (نودهای node) شبکه یا هر کامپیوتری که یک کپی از این دفتر کل را در خود نگه می‌دارد به اشتراک گذاشته می‌شود بلکه توسط خود آن‌ها نیز تایید و مورد موافقت قرار می‌گیرد. هر بلوک جدیدی که ایجاد می‌شود، قبل از آکه بخواهد تایید شود باید توسط تک تک گره‌های شبکه صحت آن تایید گردد. اینگونه جعل تاریخ معامله تقریبا غیرممکن است.
بسیاری از کارشناسان معتقند که بلاکچین ظرفیت بسیاری خوبی برای کاربردهای دیگری همچون رای گیری آنلاین، جذب سرمایه به طور جمعی (crowdfunding) دارد. علاوه بر این با توجه به نرخ پایین و سرعت بالای انتقال این ارزها از یک شخص به شخص دیگر در هر جایی از دنیا، پتانسیل بهره بردن از آن‌ها در تجارت‌های بین‌المللی بسیار بالا است، با این وجود، از آنجایی که ارزهای رمزپایه مجازی هستند و بر روی یک پایگاه داده مرکزی ذخیره نشده‌اند. در نتیجه اگر شخصی کلید خصوصی خود را گم کند، ارز خود را به طور کامل از دست خواهد داد. اما در کنار این موضوع، باید گفت که هیچ مرکز، دولتی یا شرکتی به اطلاعات شخصی شما دسترسی ندارد.

مزیت های ارز های دیجیتال

معایب ارز های دیجیتال

غیرمتمرکز بودن

انتقال ارزهای دیجیتال بین دو شخص به طور مستقیم و بدون نیاز به شخص ثالث قابل اعتماد مانند بانک انجام می‌گیرد. اینگونه هیچ دستگاه دولتی توان به کارگیری سیاست‌های پولی‌ را که ممکن است باعث ایجاد بحران مالی شود ندارد. در عوض ، این انتقال با استفاده از کلیدهای عمومی و کلیدهای خصوصی و اشکال مختلف سیستمهای تشویقی مانند Proof of Work یا Proof of Stake انجام می‌شود.

فعالیت‌های غیرقانونی

ماهیت نیمه ناشناس بودن ارزهای دیجیتال باعث ‌می‌شود تا آنها برای انجام فعالیت‌های غیرقانونی مانند پول شویی و فرار مالیاتی مناسب باشند. با این حال ، مدافعان ارزهای دیجیتال غالبا ناشناس بودن خود را با استناد به مزایای حفظ حریم خصوصی توجیه می‌کنند. برخی ارزهای رمزپایه نسبت به سایرین خصوصی تر هستند.

حفظ حریم خصوصی، شفافیت، هزینه انتقال ناچیز و سرعت بالا

ارزهای دیجیتال را باید در درون کیف پول دیجیتال نگه داشت. برای سخت کیف پول دیجیتال نیازی هیچ گونه مشخصات فردی نیست (حریم خصوصی افراد). در عین حال هر کسی می‌تواند این کیف پول را مشاهده کن (اما نمی‌تواند بفهمد برای کیست) و بفهمد که چه مقدار ارز در آن است یا چه تراکنش‌هایی انجام گرفته است (شفافیت). هزینه انتقال در شبکه ارزهای دیجیتال نسبت به بانک‌ها ناچیز است. علاوه بر این انتقال آن در هر زمانی به هر نقطه‌ای از جهان تنها در چند دقیقه ممکن است.

نوسانات بالای قیمت ارزها و از دست رفتن سرمایه با از دست دادن کلید خصوصی

تنها راه کنترل کیف پول‌های دیجیتال، در اختیار داشتن کلید خصوصی آن است. در نتیجه اگر آن کلید خصوصی گم شود، از آنجایی که هیچ مرکزی کنترل و اختیاری بر آن ندارد، همه‌ی دارایی‌های نگه‌داری شده در آن کیف پول از بین خواهد رفت. از طرف دیگر، نوسانات ارزش و قیمت ارزهای دیجیتال در حال حاضر بسیار بالا است و در نتیجه ریسک نگهداری از آن‌ها نیز بالا می‌باشد. البته سعی شده است تا با استفاده از استیبل‌کوین‌هایی همچون تتر این مشکل را برای افراد ریسک‌گریز برطرف کرد.
ارز دیجیتال چیست | خرید ارز دییجتال | فروش ارز دیجیتال | بهترین قیمت ارز دیجیتال

نقدهای وارد بر ارز های دیجیتال

قیمت و ارزش ارزهای رمزپایه بر اساس میزان تقاضا و عرضه برای آن تعیین می‌شود. در نتیجه نرخ تبدیل یک ارز به دیگری یا حتی نرخ یک ارز در طول زمان می‌تواند نوسانات بسیار زیادی داشته باشد. برای مثال بیت کوین در اواخر ماه دسامبر سال ۲۰۱۷ شاهد یک رشد و سقوط رادیکالی بود. تا جایی که ارزش آن تا حدود ۲۱ هزار دلار هم بالا رفت. بنابراین برخی از اقتصاددانان به ارزهای دیجیتال به چشم یک حباب کوتاه مدت یا سوداگرانه نگاه می‌کنند.
نگرانی دیگری که وجود دارد آن است که ارزهای رمزپایه مانند بیت کوین پشتوانه‌ی مادی ندارند. با این وجود برخی تحقیقات مشخص کرده‌اند که هزینه تولید بیت کوین که نیاز به انرژی فزاینده‌ای دارد ، به طور مستقیم با قیمت بازار آن مرتبط است.
با این وجود ، بسیاری از ناظران مزایای احتمالی ارزهای رمزپایه را نیز می بینند، مانند امکان حفظ ارزش در برابر تورم، انتقال راحتتر و تقسیم آسان‌تر به واحدهای کوچکتر (در مقابل فلزات گرانبها) و عدم وجود نفوذ بانک های مرکزی و دولت‌ها.
