The spring of digital currency
Huang Zhen, director of the Institute of financial law of Central University of Finance and economics, said that digital currency mainly refers to the form of currency and will not cause currency shrinkage. The issuing scale of money is still controlled by the central bank, while the issue of paper money or digital money is just a change of form< In addition, Huang Zhen mentioned that the issue of digital currency is still in the stage of discussion, which is an innovative mechanism of currency value symbol, and many problems are still under study. However, in practice, people are more and more inclined to use e-banking and e-payment rather than carrying notes. Under this trend, the number of banknotes in circulation in the future may decrease
the central bank's issuing of digital currency is still inspired by encrypted digital currencies such as bitcoin and lettercoin, and so is the token of European crowdfunding platform. The digital currency issued by the central bank has monetary attributes, while the token of European crowdfunding platform can only be a kind of asset certificate, a niche proct.
The central bank's digital currency is just around the corner. Public officials in the pilot areas have received salaries and subsidies in the form of digital currency, and some retail instries, such as Starbucks and subway, have also received subsidies. So what is digital currency? What is the difference between WeChat and Alipay? Let's talk about it in detail Can p>
replace WeChat and Alipay? p>
at present, China's mobile network has been very developed, so there is no advantage for bilateral offline payment. If I were, I would rather use WeChat or Alipay for electronic payment, or at least lose the mobile phone, Alipay and WeChat still have money, and the money in the bank card is still there. If you use digital currency, if you lose your mobile phone, the digital currency may be gone P>
so, in the current environment, I prefer to use WeChat and Alipay rather than digital money. p>
