Digital currency for merchants
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 assetsaccording 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 extensivelyblockchain 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 ofdata 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 ecosystemfor 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
in September 2017, the central bank issued an announcement on preventing the financing risk of token issuance, which formally determined that ICO is illegal financing without approval, and no organization or indivial is allowed to participate
later, on April 23, 2018, it was announced that the left and right digital currency ICO platforms had all withdrawn from the Chinese market, so the current ICO is illegal in China< Second, digital currency exchanges are prohibited in China.
after announcing that ICO is an illegal financing activity, the central bank also listed services such as trading, exchange, pricing and information intermediary for virtual currency as prohibited items, which means that digital currency exchanges are illegal in China
the trading platforms including bitcoin China, okcion, and fire coin all announced to stop the RMB recharge business in 2018, and closed the trading platforms one after another. As of April 2018, all digital currency exchanges have completely withdrawn from the Chinese market
Third, the central bank has not yet issued legal digital currency
so far, the central bank has not issued legal digital currency. If you are recommended to buy a digital currency "authorized or issued by the central bank", it must be a fraud platform
conclusion: there are no relevant laws and regulations for digital currency in China, but according to the documents issued by the central bank, the state is very cautious about digital currency, especially the digital currency issued by indivials.
[main answer]
at present, China does not support the circulation of digital currency, so there is no legal digital currency

digital currency is abbreviated as digiccy, which is the abbreviation of "digital currency" in English and the alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digiccy
digital currency is different from the virtual currency in the virtual world, because it can be used for real goods and services transactions, not limited to online games. The early digital currency (digital gold currency) is a form of electronic currency named after the weight of gold. Today's digital currency, such as bitcoin, lightcoin and ppcoin, is an electronic currency created, issued and circulated by check sum cryptography. It is characterized by the use of P2P peer-to-peer network technology to issue, manage and circulate currency. In theory, it avoids bureaucratic examination and approval, so that everyone has the right to issue currency
digital gold currency is a kind of physical currency, and its deposit is 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 regulatory manner. Digital gold money suppliers are not banks, so banking regulations are not applicable. However, the global digital currency Association, founded in 2002, is a non-profit association of online currency operators, convertors, merchants and users. This association supervises the users' reports and ratings the reputation of the convertor. The rating operation is confirmed by the users' reports
Suzhou will open on December 12; Double 12 Suzhou Shopping Festival & quot; Activities. Just recently, Suzhou announced that it would issue a total of 20 million yuan of digital RMB consumption red envelopes to the citizens who meet the requirements. The amount of each red envelope is 200 yuan, a total of 10 red envelopes. The distribution method is lottery. At that time, some of the citizens who signed up for the lottery will participate in the offline wallet experience. Perhaps most of them, after seeing this news, are envious of the Suzhou people; What is digital RMB; This question will be raised again and again. So, what is the digital RMB? What is the difference between Alipay and WeChat, which we usually use? The three points above strong>
are the main differences between the digital Renminbi and Alipay and WeChat. In addition, the emergence of digital renminbi will not threaten the existence of Alipay or WeChat. The digital renminbi will not completely replace banknotes in a short time. After the official launch of the digital renminbi, the public can choose to use traditional banknotes or digital Renminbi by themselves. It is reported that since May, in some areas of Suzhou, a small part of civil servants' wages have been paid in digital RMB, while most of the rest are still paid in traditional ways, so the two are not contradictory
