Discussion and exchange of digital currency

1. Yao Qian, head of the preparatory group of the digital currency Research Institute of the central bank, said that the digital currency issued by the central bank is mainly to replace physical cash, rece the cost of issuance and circulation of traditional paper money, and improve the convenience and transparency of economic transactions
Huang Zhen, director of the Institute of financial law of Central University of Finance and economics, said that digital currency mainly refers to the form of currency and will not cause currency shrinkage. The issuing scale of money is still controlled by the central bank, while the issue of paper money or digital money is just a change of form< In addition, Huang Zhen mentioned that the issue of digital currency is still in the stage of discussion, which is an innovative mechanism of currency value symbol, and many problems are still under study. However, in practice, people are more and more inclined to use e-banking and e-payment rather than carrying notes. Under this trend, the number of banknotes in circulation in the future may decrease
the central bank's issuing of digital currency is still inspired by encrypted digital currencies such as bitcoin and lettercoin, and so is the token of European crowdfunding platform. The digital currency issued by the central bank has monetary attributes, while the token of European crowdfunding platform can only be a kind of asset certificate, a niche proct.

If you want to participate in the transaction of digital currency, you must understand the digital currency ecosystem

It can be said that digital currency exchange is the most important part of the whole instry. Digital currency exchange provides investors and traders with the capital channel to buy and sell digital currency. At the same time, the trading activities of the exchange determine the price of many digital assets

according to coinmarketcap, the capital flow of digital currency exchanges is huge, with the average daily trading volume of the top five exchanges exceeding US $3 billion

there are hundreds of digital currency exchanges around the world, some of which operate globally in mainstream markets, while some focus on niche markets

for example, AAX is committed to providing services for digital currency traders and institutional investors, integrating the digital currency world with the global economy, and providing unparalleled first-class technical capabilities using the matchmaking engine supported by lseg technology

many substitutes have successfully occupied a certain market share shortly after their launch. What digital currency exchanges have in common is that they together provide the development soil for these alternative currencies

digital currency is no longer limited to bitcoin. Other digital currency assets, such as eth, XRP, BCH, usdt, LTC, EOS, xtz, etc., have a place in the portfolio and diversification strategies of many digital currency dealers

At present, there are many similarities between digital currency trading and foreign exchange trading, because the basic principles, tools, indicators and strategies used in foreign exchange are also applicable to digital currency trading. AAX College's digital currency trading section discusses these topics in depth and extensively

blockchain protocol

blockchain is the underlying technology that makes digital currency possible. There are many kinds of blockchain protocols, and the technical characteristics, advantages and disadvantages of each protocol are slightly different

for example, bitcoin blockchain relies on mining and pow (proof of work) mechanism to process transactions, while another blockchain may use dpos (proof of entrustment) mechanism instead of mining. In addition to bitcoin blockchain, other noteworthy protocols include eth, hyperledger, EOS, XLM, Iost, kin, TRX and stem. Among these blockchain agreements, ETH (Ethereum) is commendable in promoting the rapid innovation of the entire digital currency ecosystem

Ethereum platform was created by vitalik buterin, which indicates that developers can make better use of the resources of the platform by using their own programming language solidity. Ethereum has made blockchain technology all the rage, creating a new world of innovative decentralized applications on the basis of smart contracts and custom tokens. At present, most of the substitutes are based on Ethereum's erc20 standard

the district centered financial movement, or defi for short, is also basically based on the Ethereum blockchain agreement

financial services

for every service in traditional finance, Ethereum based defi applications have corresponding alternative versions for everyone to access. The defi app allows users to create stable currencies, lend money and earn interest, send and receive payments, get loans, trade, take positions in the forecast market, enter the real estate sector, and so on. Smart contracts are the key to making decentralized services possible. Once certain conditions are met, the smart contract will automatically perform the pre agreed activities

at the same time, traditional finance also began to provide new customized services for the field of digital currency. At present, some fund managers provide investors with the option of adding digital currency into their portfolios, the trustee provides security services for investors who invest a lot of money in digital currency, and many analysts in mainstream media (such as Bloomberg) also have a strong interest in digital currency

digital currency hardware

for those who like to build their own security measures, the huge digital currency hardware market can provide professional traders and long-term holders with the tools they need. Trezor and ledger are the most famous hardware wallets. They essentially provide the same value for digital currency traders, that is, a more secure way to store digital currency

of course, digital currencies stored in hardware wallets cannot be traded in the market. Therefore, digital currency traders usually allocate funds between the hardware wallet and the exchange according to a certain ratio according to their own trading style preference

There are so many activities of

data aggregators and blockchain analysis

cross blockchain, which proces a large amount of data, and also spawns the emergence of sub instries, namely data aggregators and blockchain analysis instries. Companies such as coinmarketcap are the preferred source for quick inspection of digital currency and exchange data. They collect statistics on trading volume, liquidity, market value, price trend, circulation and the whole instry, such as the total amount of money, the number of markets, the market value of the instry and the proportion of BTC market value

people who are more interested in blockchain analysis can find the required data in websites like blocktivity. Here, you can view the relevant data of each indivial blockchain agreement, including the number of operations in the last 24 hours, the average number of operations in the last 7 days, the market value and Cui index, that is, the remaining available capacity after the actual usage of the current blockchain agreement. All in all, these websites can provide valuable insights for the blockchain instry

for example, the average number of operations of Ethereum in the past seven days was 667000, with Cui slightly higher than 50%, while the average number of operations of EOS in the same time range was 63 million, with Cui slightly lower than 50%. Technically, the performance of EOS protocol is more powerful than that of Ethereum. However, this can not prevent Ethereum from occupying 70% of the total market value of the most mainstream currencies

digital currency media and conferences

in today's world, almost everyone is the publisher of content. Without we media instry, such a large-scale instry will no longer exist. Digital currency has given birth to a wide range of media patterns, covering news media, KOL and related conferences for currency, public chain and code

digital currency head media include coindesk, cointegration, bitcoin magazine, decrypt, CCN, bitcoinist, newsbtc, etc. Some KOLs are also well-known, sometimes even more popular than the news media

YouTube celebrities, such as datadash, dollar villante, altcoin buzz, Ivan on tech and boxmining, have subscribers from 200K to 300K. In the field of digital currency trading, the top stars of cryptotwitter include venture coinist, cryptocred and cryptodon alt, with 211k, 140k and 120K fans respectively

if you want to have face-to-face communication with companies and people, digital currency and blockchain meetings should not be missed. Every year, there are many conferences around the world for investors, blockchain experts, start-ups, institutional financing, currency or agreement related communities. In 2019 alone, we sponsored and participated in blockchain live in London, the capital summit hosted by coinmarketcap in Singapore and the world mobile conference in Shanghai. We have had exciting meetings with other digital currency companies and major financial institutions, and established contacts with regulators from different jurisdictions

digital currency supervision

with the continuous growth of the market and audience of digital currency instry, in most cases, financial regulators are still developing relevant frameworks to protect investors and consumers. Regulators may take a very different approach, which is a challenge for companies operating across multiple jurisdictions

ring the ICO boom in 2017 and 2018, many projects were launched before the regulatory framework was established, while some projects did not meet the criteria of the jurisdiction and were suspended ring the fund-raising process. All this comes from how to classify digital assets, and the understanding of classification is constantly changing. At present, we divide digital assets into security token and practical token

in the past year, with the proposal of Libra, the promotion of supervision is also increasing. The central bank is also actively exploring the significance of blockchain technology to its policies and economic activities, and constantly publishing reports

the rapid development of digital money ecosystem

these components of digital money ecosystem are growing and developing in an orderly way, contributing to the increasingly sound instry. From the minority interest in 2009 to the active digital asset economy, digital currency has come a long way

However, in order to achieve the development and wide participation of the instry, a strong ecosystem is not enough. We need a better link between digital money and global finance. The better the combination of digital currency and traditional finance, the easier it will be for newcomers to understand the digital currency ecosystem

for every novice, as exchanges, financial services, media and regulators graally adapt to the expectations of mainstream consumers, the digital currency instry will further develop, which may improve investment outcomes

3. March 20, 2016 is not a major day for digital currency, and nothing big happened in the digital currency circle. There is also a big digital currency summit or exhibition in Shanghai on this day. However, in the direct marketing circle

4. 1. If you want the market of the mine, unless you are very lucky to have a man in your suit to see your problem and he is a good man ~
2. Otherwise, you can't observe the market for a few days by yourself in the auction house! Maybe it happened that all the cheap mines were collected by XX that day, and then a group of JS put a lot of high priced ones ~
3; Making the most of money & quot; You don't have to work so hard to mine! You work hard to finish the task at level 70. When you have time, you may have 5000 or 6000 g at level 70. I believe! It's more than 3000 g to do tasks from 60 to 70. I (still have two maps to do)
4. It's not a difficult thing to wash mines now. In fact, when you practice level tasks, the small map is open to detect minerals, and each mine is mining, and the mine rises faster than you ~
5. Don't want to waste, right? If you don't want to waste it, you can turn enchantment into engineering ~
supply and demand ~
enchantment is not recommended (if you are a leisure player ~ at least I am) because it's money burning if you can't do it well. Don't be stingy with low-grade mines, such as direct stores of stones. The rare ones can be put into auction houses. You can't make much money by buying those low-grade mines, Why don't you spend all that time worrying about whether you want to spend a lot of time in the low-level ore auction house on the level flushing skills? World of Warcraft is a very easy thing
6. The condition of my clothes is that the raw stone is better than that after smelting, and the sales area is smaller after smelting ~ personal feeling
7. Back to the point, to make money, you should quickly reach level 70! Daily mission can provide nearly 300g ~! What concept
don't worry! World of Warcraft won't make it that easy for you; Poor & quot; Yes! Don't just believe that only mining can make money---& gt; Do the task & lt---- The real way to make money (from the perspective of leisure)~

5. When an instry is rising, the first wave is platform and traffic, and then the various applications. And like anti-counterfeiting traceability and supply chain, I am very optimistic about TAC traceability chain.

6. Except the DCEP of the central bank, all digital currencies are illegal. Do you want to communicate with the judge

7.

It can not be said to be a fraud, but there are certain risks, because digital gold currency is a form of physical currency, and its deposits are measured in gold rather than legal currency. Therefore, the purchasing power fluctuation of digital gold currency is related to the gold price. If the price of gold goes up, it becomes more valuable. If the price of gold goes down, it loses value

since there is no specific financial regulation to regulate digital gold money suppliers, they operate in a self-regulation way. Digital gold money suppliers are not banks, so banking regulations are not applicable

extended data

to explore the connotation of digital currency, we must clarify some concepts of model lake. For example, is it legal digital currency dominated by the central bank or illegal private fixed digital currency; Encryption of digital currency or electronic currency; Is it "selling dog meat with sheep's head"; "Bad money"

new technology does make the conceptual boundary of money more blurred. Theoretically speaking, the new monetary economics points out the possibility of the disappearance of money, that is, legal paper money is no longer the only medium of transaction, and is eventually replaced by financial assets issued by the private sector that generate monetary income

in reality, although the status of fiat money is still unshakable, there have been various local scenes of private money in history, such as the universal warra system in Germany in the 1920s. Now the digital currency with the characteristics of decentralization makes the challenge of private currency increasingly prominent< br />

8. From April 18 to 21, the Boao Forum for Asia 2021 annual meeting was held at the Boao Forum for Asia International Conference Center in Hainan. During the meeting, Li Bo, vice president of the people's Bank of China, held a speech at the Boao Forum for Asia & lt; Digital payment and digital currency; When making a video speech at the sub forum, he talked about the supervision of bitcoin and stable currency, and made a clear definition of bitcoin; Bitcoin is an encrypted asset and an investment option. It is not a currency, but an alternative investment& rdquo; He believes that encryption assets may play a major role in the future as an investment tool or alternative investment. As an investment tool, many countries, including China, are studying its regulatory environment

The cross-border payment of digital currency is not an easy task. The cross-border payment of digital currency is not only a technical problem. Each country has its own macro-control needs. It is necessary to ensure the independence of monetary policy and do a good job in anti money laundering and anti-terrorism financing. In addition, the exchange rate system of each country is not the same. We should also respect the monetary sovereignty of central banks, not pursue a particular currency; To rule the world;. It is necessary to build a healthy ecosystem and form a special payment corridor in order to control the possible impact of the pilot project within a controllable range, or slow down its possible impact. As far as the specific implementation methods are concerned, there are three ways in the meeting. One is to make different central bank digital currencies compatible with each other, that is to say, different systems can be connected; One is to establish some interconnection lines to create a more closed-loop system. Different central bank digital currencies can establish seamless connection through different interfaces and interfaces; There is also a most radical approach, that is, to create an integrated system to accommodate different central banks' digital currencies and put them into the same operational framework

However, in the future, digital currency and cash will be in parallel and graally replaced for a long time. When the era of digital currency really comes, people will carry less and less cash, travel more and more safe, poverty alleviation more and more accurate, corruption more and more difficult to escape, and thieves more and more difficult

9. The highest model of CPU is more than 1000 pieces at most, more than 800 pieces of graphics card are renovated, and the power supply is not any. The memory mole for playing cards should be renovated DDR3 memory. Motherboard is a foreign garbage renovation
so these things are so cheap. They seem to be very powerful. In fact, they are mostly used to renovate second-hand shrinking machines.
thank you
