The possibility that virtual currency will completely replace circulating currency in the future is very low. We can't forget the origin of currency: the medium of daily circulating goods, because when people exchange things for things or a certain service behavior, a medium that needs everyone's approval and acceptance is produced, and this medium can be accepted by everyone because it has a certain value base. The prerequisite for this value is that the social relations of production are the result of * * * in the constantly evolving period, and the formulation of a single value standard is usually the government authority in a certain region of a country. The economic level of different countries in different regions of the world is different, so the monetary value is also different, and there is no unified value standard.
