Is central bank digital currency promising
In the morning of March 9, 2014 Beijing time, Jared Cohen, creative director of Google, said at the Sxsw conference this week that digital cryptocurrency similar to bitcoin will exist for a long time. Cohen and Eric Schmidt, Google's chairman, promoted their co-author book the new digital age at the conference
in the past few months, bitcoin prices have fluctuated significantly. At the same time, this digital currency is strongly supported by the hacker community and is closely related to some black markets. Cohen believes that bitcoin has its value, but it will bring risks if it is not regulated
mt.gox lost $400 million worth of bitcoin, which shakes the confidence of the outside world in bitcoin. Some critics even point out that "bitcoin is dead". However, Cohen's statement is a strong support for cryptocurrency technologies such as bitcoin
bitcoin can exist only because both sides of the transaction recognize its transaction value, so anyone can independently design a virtual currency. Ars technica, for example, announced this week that it would create its own cryptocurrency, arscoin
Cohen believes that the main threat to digital cryptocurrency is how to keep it safely, and the loss of mt.gox bitcoin once again highlights this problem. Recently, the US Congress has also launched a debate on digital cryptocurrency. Some members believe that the supervision of the bitcoin should be strengthened to avoid risks. Another congressman, Jared polis, believes that the US dollar has similar defects to bitcoin, so if bitcoin is banned, then the US dollar note should also be banned
digital currency has a short history in the world, but it develops rapidly. Many countries are trying to sum up experiences and lessons through official or non-governmental efforts
take Europe as an example. In 2015, the transaction volume of digital currency in relevant European countries and regions exceeded 1 billion euro. Although the total amount is not large, it is fierce
it was reported on January 2, 2016 that the Bank of England is also considering whether to issue digital currency by the central bank, and the research work is still in the initial stage. Andy Haldane, chief economist of the Bank of England, said that switching to digital currency would be "a great technological leap forward"
DNB, Norway's largest bank, has already cancelled the cash counter service. The bank called on the government to stop using paper money completely. According to the data, only 6% of Norwegians still use cash every day, most of them the elderly. The social cost of cash payment is twice that of electronic money payment. In one day's life, the payment of bus, shopping, payment, refueling, and even parking is completed by swiping the card. Only when the children's school holds a charity sale can the banknotes be used
compared with paper money, digital currency has obvious advantages, which can not only save the cost of issuance and circulation, but also improve the efficiency of transaction or investment, and enhance the convenience and transparency of economic transaction activities. The issue of digital currency by the central bank also ensures the continuity of financial policy and the integrity of monetary policy, and also ensures the security of monetary transactions
although the issuing method of digital currency is still under study, paper currency has been regarded as "the currency of the previous generation" by some professionals, and it is the general trend to be replaced by new technologies and procts. Due to China's large population and volume, the timetable for issuing digital currency is still uncertain. It is predicted that digital currency and cash will be in parallel and graally replaced for quite 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
the Central Bank of China held a seminar on digital currency at the beginning of this year, and the issue of digital currency by the central bank has been put on the agenda. Some international banking giants and technology companies are also developing digital currency, and the Bank of England also plans to issue digital currency. All this means that digital currency is getting closer to our real life. However, the digital currency issued by the government may be in circulation in the future, but bitcoin, Ruitai currency and vitality currency can only exist as an asset class.
popular science: digital currency (digiccy) is an alternative currency in the form of electronic currency. Both digital gold coin and password currency belong to digital currency. It can not be completely equivalent to the virtual currency in the virtual world, because it is often used for real goods and services transactions, not limited to online games and other virtual space. At present, the central bank does not recognize or issue digital currency, and digital currency does not have to have a benchmark currency. The popular digital currencies in 2015 include bitcoin, lightcoin, bitstock, etc. At present, there are thousands of digital currencies issued all over the world.
1. High liquidity
every good and reliable digital currency is essential. Every digital currency should have strong liquidity, not only in the scope of third-party trading platform, but also in offline entities or countries like bitcoin
Second, lower volatility
generally, volatility comes from the influence of third-party trading platform, which is similar to stock trading. Strong operators need to control the market to prevent the digital currency market from soaring or plummeting. Therefore, the volatility of a digital currency can show whether the digital currency can develop stably
Third, tradability one of the most important properties of digital currency is tradability. If a digital currency does not have tradability, the digital currency is basically useless. Only when a digital currency has tradability can it have liquidity and volatility Fourth, the nature of decentralization digital currency has the characteristics of decentralization. Digital money is neither controlled nor manipulated by centralized entities. That is to say, no indivial or third party can obtain the user's digital currency Fifth, the value of digital currency is increasing based on the market demand. It is not subject to government regulation or operation, which is not like legal money. The rise and fall of digital currency price depends on the transactions between users on the third-party trading platformDigital currency is an unregulated and digital currency, which is usually issued and managed by developers and accepted and used by members of a specific virtual community. The European Banking authority defines virtual currency as a digital representation of value, which is not issued by the central bank or authorities, nor linked with legal currency. However, because it is accepted by the public, it can be used as a means of payment, or it can be transferred, stored or traded in electronic form
in recent years, the excessive issuance of banknotes has led to the aggravation of inflation, the frequent security crisis of third-party payment, and the graal maturity of blockchain technology, so decentralized digital currencies such as bitcoin, Ethereum and reborn have emerged. Digital currency has the advantages of low transaction cost, fast transaction speed, high anonymity and fixed amount of money
At the same time, the use scenarios of digital currency become more and more abundant, which makes the user acceptance grow. At present, the use of digital currency has covered all kinds of scenes, such as shopping consumption, wage payment, transportation, travel, takeout settlement and tuition payment. The expanding landing scene has also brought a wider range of consumers. In general, although the number of users of digital currency still accounts for a small proportion of the total population, the number of users is growing. At present, the utilization rate of digital currency has exceeded 10% in 10 countries around the world In June 2019, Facebook launched Libra virtual cryptocurrency, which has caused worldwide influence. The emergence of Libra may form a global super sovereign currency, thus affecting the traditional transaction settlement currency. For China, the emergence of Libra, on the one hand, will have an impact on China's traditional currency and threaten the sovereign status of China's currency; On the other hand, because RMB is not included in Libra's basket of currencies, it will rece the reserve demand of RMB by central banks, thus hindering the internationalization of RMB. In response to this threat, CCTV timely launched the central bank digital currency. In September 2019, according to China Daily, the central bank's digital currency closed-loop test has begun, and the central bank's digital currency is about to come outcoincidentally, in addition to China, central banks around the world have also announced that they will launch a centralized digital currency based on national credit. In 2015, Ecuador took the lead in launching the national version of digital currency, which can not only rece the issuance cost and increase the convenience, but also enable people in remote areas who cannot have banking resources to obtain financial services through the digital platform. At present, Canada, Brazil, Norway, the United Kingdom and other countries are studying the central bank legal digital currency, while the Bahamas, Sweden, Russia and other countries are discussing the possibility of digital currency issuance. Generally speaking, the developing countries which have received a great impact on digital currency have supported legal digital currency for financial inclusion, breaking through sanctions and other reasons
