3. In the era of physical money, money itself has intrinsic value, so it can perform these functions of money. However, modern credit money or paper money itself has no value, why can it perform the function of money? This is because the credit currency is supported by the national credit, which has the nature of legal compensation and compulsion. National credit is not only the value basis for the standard currency to perform its monetary function, but also the basis for the state to monopolize the right to issue currency< At the same time, monetary policy is an important means for modern countries to adjust their economy. The change of money supply has a wide influence on economy. Nowadays, central banks all over the world make full use of monetary policy to regulate economic operation
monetary policy, like tax, police, court and other state machines, is the foundation of modern state operation and an important part of state machine. As long as there is no fundamental change in the social organization form of the state, the monetary system based on the national credit will always exist, and bitcoin and other virtual currencies will not become the standard currency of a country. Bitcoin is actually just the use of technology, which is at most an asset, not a real currency< Of course, credit money is prone to inflation. In a sense, people's concern about bitcoin reflects people's worry about inflation under the condition of credit currency. Therefore, central banks should strengthen liquidity management, reasonably regulate money supply and keep prices basically stable.

However, digital currency can further rece operating costs, and can be applied in a wider range of areas with higher efficiency
"the emergence of digital currency follows the inevitable law of currency evolution, and is also the inevitable result of the development of science and technology. From the perspective of historical process, the carrier of currency has evolved from shellfish and precious metals to paper money, and then to the popular third-party payment electronic currency in modern society
in essence, they are pursuing the convenience and low cost of transaction, and this trend continues to develop, and the manifestation in the future society is digital currency. The first thing to solve is the technical barriers, although today's blockchain is regarded as the Internet of the 1990s, and its future is limitless. But it is not mature enough to support the huge payment system. At the same time, the issuance of legal digital currency will greatly increase the number of point-to-point transactions, bypass the original regulatory system to a certain extent, and easily facilitate illegal transactions. As digital currency makes it very convenient to convert deposits into cash, financial panic and financial risk will accelerate the spread once they occur, which increases the difficulty of supervision. In addition, in the process of using legal digital currency, a large number of user data and transaction information will be obtained. How to store and manage these data to prevent the disclosure and illegal use of user information is also an important challenge.
