I never thought about using digital currency

1.

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

2. Cheng is one of the pilot cities of digital currency, but it has not yet begun to circulate. Shenzhen is the first city to circulate, with a face value of 200 yuan
digital currency has four common functions: "scan code to pay", "remittance", "collection and payment", "touch one touch"
the pilot cities are Shenzhen, xiong'an, Cheng and Suzhou
the glorious revolution. The king's name is William III and Mary II. Mary is the daughter of James II of the Stuart dynasty. William III was originally in power in the Netherlands. Mary's husband also has the blood of Stuart family. James II is a Catholic, trying to restore the status of Catholicism in England. When James II ascended the throne, he was very old. At that time, it was generally believed that his Protestant daughter would inherit the throne after James II died (when James had no son). The Whig party, which controlled the Parliament, thought that this would not affect the status of the Church of England, But later, James II united with the king of France to try to restore the status of Catholicism in Britain and the power of the king. At that time, Britain and France were hostile to each other, and Louis XIV's foreign expansion policy made the Netherlands, Britain and other countries united against France. James II's practice intensified the conflict between the king and the parliament. During this period, James II got a son in his old age, which made England under the leadership of a Catholic king in the future. Worried that it would harm the interests of Britain, Parliament planned to make Anne and William king of England. On the other hand, it was ring the so-called great alliance War (the nine-year war, see Cambridge Modern World History, omitted here) that William, the ruling Dutch, urgently needed the strength of Britain to help him fight against France, so that his plan could be carried out. James II fled to France and Ireland when he learned that the Parliament had given William the throne. With the support of France, he organized an army to attack the British army. Later, he was defeated in Ireland and fled to France. Later, the British Parliament passed a series of laws to consolidate this form. The British double king rule lasted until 1694 (Mary II died). In 1702, Anne, another daughter of James II, succeeded to the throne. After Anne died, the throne was transferred to Hanover, Germany, and the Stuart dynasty ended.

3. It is wrong to say that China's digital currency comes from the people, because it comes from the present. Science.

4. Go language has not shown a clear direction since its appearance. Google employees call it an "experimental language", saying that it tries to integrate the development speed of dynamic languages such as python with the performance and security of compiled languages such as C or C + +. A supporter of go language summarizes that go language is as follows: simple, fast, safe, concurrent, happy programming, open source; But go language lacks direction and the attempt of its "synthesizer" will easily lead to its failure to learn from cats and dogs, and become a four unlike. Nevertheless, the editors still think that go language has great potential: many developers are interested in it - not only its original designers have a strong lineup, but also the people involved in modifying the source code. This is likely to help go language find its own direction and open up a new direction of system programming.

5. Digital currency is of great significance in asset allocation. One of the characteristics of digital currency is that its correlation with other traditional assets is close to zero, which is very low, and low correlation varieties can often be seen as a tool for investment diversification. When the traditional market encounters extreme events, digital currency has the function of value preservation. So I prefer to use digital currency as a hedging tool. At present, 10% of my assets are invested in bitcoin on the okex exchange. Please accept my answer. Thank you very much. If there is any need, you can ask, thank you!
