at present, digital currency is more like an investment proct, because it lacks a strong guarantee agency to maintain its price stability, and its role as a value measure has not yet appeared, so it can not be used as a means of payment. As an investment proct, digital currency cannot develop without trading platform, operating company and investment company
digital currency is a double-edged sword. On the one hand, the blockchain technology it relies on has been decentralized and can be used in other fields except digital currency, which is one of the reasons why bitcoin is popular; On the other hand, if digital currency is widely used by the public as a kind of currency, it will have a huge impact on the effectiveness of monetary policy, financial infrastructure, financial market and financial stability

Cardano (ADA)compared with Ethereum, EOS and Tron, Cardano is the third generation of decentralized app (DAPP) and smart contract platform. Cardano's design philosophy has the following points:
scalability: with the growth of users, the transaction processing speed is not affected or even faster, such as P2P protocol
interoperability: in the future, there will be countless devices connected to each other, instead of only connecting and forwarding through routers. All kinds of devices can communicate directly through standard general protocol
Sustainability: like bitcoin, Cardano project will not be controlled and influenced by a certain company or organization, which is a safe, decentralized and sustainable development platform

the effect of advertising is restrained: middlemen earn most of the fees, a large number of advertisements are blocked by users using software, and advertisements are fake
in the past six to 12 months, the number of publishers using the brand browser (Note: the brand browser supports bat token) has grown rapidly, and almost no blockchain ecosystem has grown so fast

companies including Google are supporting the development of chainlink. Here is a list of chainlink partners
one of the main problems of chainlink is similar to Ethereum. The development team has reserved 650 million link tokens, while only 350 million are in circulation at present
Ethereum (ETH)Ethereum has long occupied the second place in the top 100 cryptocurrencies. Its ecology is so big that we can't call it altcoin now. To tell you the truth, I'm not optimistic about Ethereum in the long run, but it will flourish in the short run
according to the news on August 10, Mu Changchun, deputy director general of the payment and Settlement Department of the people's Bank of China, said at the third China finance forum that the central bank's digital currency will soon be launched and will adopt a two-tier operation system, that is, the people's Bank of China will be the upper tier and commercial institutions will be the second tier< As for why the central bank's digital currency chooses the "two-tier operation system", Mu Changchun explained:
1. The central bank's digital currency is bound to face the retail scene and the public, while the performance of bitcoin and Libra can not meet the high concurrency. After a period of research, it is decided to adopt the two-tier system
2. It is a complex system engineering for big countries to issue central bank digital currency
3. The IT infrastructure application and service system of commercial banks and other institutions have been relatively mature, the user base is huge, and the service habit has been formed; There are plenty of talents and it experts; The system has strong processing ability, and has accumulated some experience in the application of financial technology
4. Through the design of two-tier operation, risk can be avoided to concentrate on a single indivial
5. Single layer investment will lead to "financial disintermediation". If the central bank directly releases digital money to the public, it will crowd out the deposits of commercial banks and affect the loan delivery ability of commercial banks; In extreme cases, it will also subvert the existing financial system, leading to the "grand unification" of the central bank
6; It will not affect the existing monetary policy transmission mechanism
7. The central bank will not preset the technology route, any advanced technology may be used in the research and development of the central bank's digital currency; The boundary between electronic payment and central bank digital currency is fuzzy; It can fully mobilize market forces and realize system optimization through competition
it can be seen that the central bank has recognized the legitimacy of bitcoin and Ethernet in disguised form. However, the central bank's digital currency is different from the traditional blockchain digital currency. It is 1:1 anchored RMB. I regard it as RMB digitization. The central bank's digital currency, paper money, coins and bonds exist at the same time, but in different ways. It is a kind of stable currency, and there is no room for speculation
at the beginning of this year, the most influential event of digital currency is Facebook's upcoming launch of digital currency Libra. If successful, it will bring 3 billion Facebook users into digital currency. However, Libra has not included the RMB in its basket of currencies. Coupled with the sweater war and exchange rate war with the United States, this may be the reason why the central bank urgently launched the central bank's digital currency. It is said that Wal Mart will also launch digital currency. With JPMorgan's issuing currency before, it can be predicted that traditional business giants will enter the era of blockchain digital currency one after another
the issuance of digital currency by the central bank may be a great benefit to the users of China's currency circle. Due to some policy reasons, the users' access to the digital currency world is not very smooth, which is the problem of difficult access to money. The most common stable currency, usdt, does not seem to be very stable and over issued seriously. In addition, the attorney general's office in New York investigates TEDA and other reasons, There may be a risk of thunderstorm at any time. According to statistics, about 80% of the users who use usdt are Chinese users, while the United States uses USD directly, and a few will use usdt. If the central bank introces digital currency, it will greatly facilitate digital currency users
finally, the other role of the central bank's digital currency is cross-border trade settlement. If it is combined with Alipay and WeChat payment, it will compete abroad and compete with Libra internationally.

Bitcoin was born on January 3, 2009, which has a history of 10 years. The value of bitcoin has soared from zero to US $19850, the highest point in 2017. And most people have been concerned about cryptocurrency and bitcoin since then. Before that, most people would think that bitcoin was just an "internet currency", similar to q-coin
but after the sharp rise of bitcoin in 2017, more and more people began to pay attention to cryptocurrency, understand cryptocurrency, invest in cryptocurrency, and long for cryptocurrency to bring rich economic returns. However, after several in-depth studies, bitcoin is the only cryptocurrency with value and significance. The reasons are as follows:
the total supply of bitcoin is constant. As time goes on, bitcoin will become more and more rare and become a very good means of value storage, similar to gold. In the past 10 years, this function of bitcoin has become a consensus
bitcoin is the leader in cryptocurrency, which is an absolute consensus in this instry. Looking back over the past few years, among the top ten cryptocurrencies in terms of market value, only bitcoin has always been the first, and the remaining counterfeit currencies are all in the past
one is completely closed, has nothing to do with real economy and can only be used in specific virtual communities, such as world of warcraft gold
Second, it can be purchased in real currency but not converted back to real currency, which can be used to purchase virtual goods and services, such as Facebook credit
thirdly, it can be exchanged and redeemed with real currency according to a certain ratio. It can purchase both virtual goods and services and real goods and services, such as bitcoin [2]
transaction mode
at this stage, digital currency is more like an investment proct, because of the lack of a strong guarantee agency to maintain its price stability, its role as a value measure has not yet appeared, and it can not be used as a means of payment. As an investment proct, digital currency cannot develop without trading platform, operating company and investors
trading platforms act as trading agents, and some of them act as market makers. The profits of these trading platforms come from investors' transaction or withdrawal fees and premium income from holding digital currency. Bitstamp, gathub, ripple Singapore, snapswap, Japan's Mt. GOx and China's new star Ruihu are the platforms with large trading volume [4]
the process of digital currency trading through the platform is as follows:
(1) investors should first register their accounts and obtain digital currency accounts and US dollar or other foreign exchange accounts
(2) users can buy and sell digital currency with the money in their cash account, just like buying and selling stocks and futures
(3) the trading platform will sort the buy requests and sell requests according to the rules and start to match them. If they meet the requirements, the transaction will be concluded
(4) a buy or sell request may be partially executed e to the difference between the buy and sell volumes submitted by users.
