The essence of digital currency is not the general equivalent

1. The virtual currency on the Internet can be regarded as a general equivalent, but it is not necessarily an equivalent in essence. For example, bitcoin, Ruitai coin, Qianjin card and other digital currencies can be used as general equivalents, but in essence they are not necessarily
the commodity separated from the commodity serves as the unified value expression material of all other commodities. Its appearance is the inevitable result of the development of commodity proction and exchange. Historically, the general equivalent was undertaken by some special commodities. With the progress of society, gold and silver have become the most suitable currencies to perform the function of general equivalent. Money is a special commodity separated from commodities and fixed as a general equivalent.

With the development of social proctive forces and social division of labor, the exchange of things is constantly expanding, and more and more kinds of commodities participate in the exchange. A commodity can be exchanged with a variety of commodities

the obvious disadvantage of barter is that barter requires both sides to need each other's goods in order to succeed, otherwise the exchange cannot be carried out. In order to overcome the difficulty of barter, people have found a way in the long-term practice of countless exchanges

the general equivalent is a commodity separated from other commodities, which can exchange with all other commodities and show the value of all other commodities. Generally, what kind of commodity is used as the equivalent is the same in different regions, and there are different periods in a region. In history, livestock, cloth, shells, grain, salt, metal and so on all served as general equivalents

Finally, the general equivalent becomes the medium of commodity exchange and plays the role of currency. However, it is not money. Only when the function of general equivalent is stable on precious metals, can it develop into money.

extended data:

understanding of money:

in essence, money is the contract of exchange right between owners, and different forms of money are unified in essence. In the past, e to people's unclear understanding of the nature of money, people mistakenly divided money into different categories from different angles

For example, according to the commodity value of money, it can be divided into debt currency and non debt currency; According to whether the exchange ratio of precious metals is agreed, it can be divided into convertible currency and non convertible currency

In terms of form, money can be divided into physical money and formal money according to the commodity value of money. Physical money itself is a kind of special commodity, including the amount of value, such as sheep, precious metals, etc; The formal currency itself has no value, its value is contractual, only contractual value

the two forms are different, but they are unified in essence, that is, they are both agreed as the medium of exchange, and both have contractual value. The purchasing power of money depends on the contract value of money, but the purchasing power of physical money is also affected by its own commodity value. Generally, the commodity value of physical money is less than its contract value as money

In middle school textbooks, the essence of money is generally regarded as a general equivalent

The following is the debt theory about the essence of money, that is, they think that money is a kind of creditor's right of the holder to the issuer, which is obviously flawed and can not answer the basic questions such as why the issuer borrows rights and how to repay them
