Personally, I think the implementation of digital currency is quite good. I think that in the future, I will travel around the world with my mobile phone, enter my password, verify my fingerprints, and match my face in a database, so that I can pay all my wealth without carrying my wallet everywhere. Although WeChat Alipay seems to be quite common at present, we have seen using WeChat to pay for buying stocks, buying houses and buying cars for foreign exchange. The central bank may use Alipay and WeChat platforms to expand its influence, but the essence is different. One essence is that paper money is digital. This development will greatly stimulate the speed of currency circulation and complete transactions efficiently. However, there are some technical difficulties in implementation. One is how to encrypt in digital currency, which is enough to exclude folk self-control, and the other is that it conforms to international standards and does not conflict.
The virtual currency mentioned here is the result of the expansion of populism into the financial field. Pure decentralization is actually changing from one center to countless centers. One algorithm forms a currency, but what about the other algorithm? There are millions of algorithms. Assuming that virtual currency replaces credit currency, there will probably be millions of currencies in your mobile phone. What virtual currency can be widely recognized by everyone? And according to the algorithm, the total amount of virtual currency is certain, so how to meet the ever-expanding trading demand? Virtual currency lacks government macro-control, so how to avoid the economic uncertainty caused by the proliferation of virtual currency? Perhaps with the development of science and technology and the change of society, virtual currency will enter the historical stage, but it will not be widely used for a foreseeable period of time.
To sum up, the development of digital currency should soon enter the public life and bring us convenience. The prospect of virtual currency remains to be considered. As for the limitations of personal understanding, it is impossible to understand that virtual currency can be widely used.
