Can digital currency replace paper goods
as far as I know, there is a big difference between the use of digital currency and traditional paper currency. The purpose is the same, but the technology, security and application are different. The simplest difference is that one is printed on paper, and the other is printed on the blockchain information system in digital form 
there are two simple understandings: currency digital currency is in the form of e-wallet, and RMB is paper currency. When it is used, one is to exchange currency and goods directly, and the other is to use digital currency wallet for transaction and transfer. Digital currency is certainly more convenient, while paper currency will have many problems, such as ring the epidemic, We should try our best to rece the risk of paper money transaction
however, the digital currency planned by the central bank is also different from bitcoin, Leyte, decent and other digital cryptocurrencies, but it will be used for reference.
without this calculation, the whole system is not secure, so these seemingly meaningless calculations are to ensure everyone's security
at present, virtual digital currency is still in the stage of transition, research and development, and testing, and has not been recognized by the whole world, although some countries have started the relevant research process, and even will issue their own digital currency but there is a premise of digital currency, which is decentralization. A decentralized digital currency without control means cultural differences to a country
{rrrrrrr}
Second, the electronic currency will be more convenient for people's proction and life, which is determined by the convenience and liquidity of currency. The replacement of metal currency by paper currency greatly facilitates people's proction and life, and the replacement of paper currency by digital currency is also determined by its characteristics. Third, from the social and economic point of view, digital currency has security, rapid circulation and environmental protection, which is lacking in paper money. The use of digital currency can improve the economic efficiency of the whole society and make the economy more active
Mobile payment means that mobile clients use electronic procts such as mobile phones to make e-money payment. Mobile payment creates a new payment method and makes e-money popular. Because of the advantages of convenient and fast payment, eliminating counterfeit money, no change and so on, it is loved by many people< The Ministry of Commerce issued the "overall plan for the pilot project of deepening the innovation and development of service trade in China", and officially announced that the number of digital currency has expanded from the original 4 pilot cities to 28 , which means that digital currency is coming towards us. The same virtual currency and bitcoin, so these virtual currency can replace the status of paper money
Therefore, it is essentially no different from the paper currency RMB, and will not be wildly hyped like bitcoin. In a short period of time, virtual currency can not completely replace traditional currency. There are mainly two constraints: the first is the user's will, not everyone is used to this payment method; the second is the satisfaction of technical conditions, because the speed of transaction payment is mainly limited by the technical realization, and the goal of digital currency is only to replace part of the cash in circulation. So for a long time, it should be used in parallel with banknotesin the future, digital currency may replace paper currency
the implementation of currency digitization has the following advantages: first, it can save a lot of manpower and material resources, especially rece the consumption of trees, and realize green finance without printing paper money. Second, it can accelerate the internationalization of RMB. Now, the Alibaba platform has covered many countries and regions in the world, and the settlement methods such as Alipay and WeChat have been widely used in many countries. China's timely introction of legal digital currency can connect international settlement with daily payment and attract more countries to use "digital RMB". Third, it can promote the progress of social civilization. When the paper money withdraws from human vision, "money fetishism" will die out rapidly. Especially when all currency flows are under network monitoring, abnormal currency flows will attract the attention of regulatory and disciplinary departments. This will make bribery, bribery, fraud and other violations of law and discipline to be effectively restrained, so that politics will be more clear and society will be more fair. Fourth, it is concive to the "virtual currency" rights and interests of citizens. For example, qq COINS, game coins, virtual gold coins and valuable points of various forums and websites all have a certain gold content, and can also be exchanged for equivalent goods from the issuer. The implementation of digital currency is concive to opening up the trading channel between virtual currency and legal tender, and facilitating holders to convert virtual currency into legal tender at any time. The money regulator, such as the central bank, will be responsible for the supervision or debt recovery of virtual currency issuers, so as to ensure the legitimate rights and interests of virtual currency holders.
