bitcoin is a virtual currency, and the total amount is set at 21 million, and the total amount is fixed. Bitcoin players can buy special video card miner to excavate bitcoin, and halve the number of mining bitcoin every four years until 21 million pieces have been excavated

so far, bitcoin has been halved twice, more than 17 million pieces have been excavated, and only about 4 million pieces remain to be excavated. According to some estimates, the last bitcoin will be excavated in 2140

General currency is decided by the central bank and virtual currency is decided by indivials. The sovereignty of general currency is in the center of the Republic; The sovereignty of virtual currency lies in distributed indivial nodes

from the perspective of information economics, general currency is a special case of virtual currency. The special point of this special case is:

first, the reference point remains unchanged. Therefore, value is specialized from a set to a recible value. When the reference point remains unchanged, value is equivalent to utility

Secondly, the gain and loss of utility relative to the reference point remain unchanged. This means that the value of reference point is a stable rational value and equilibrium value. In a rational economy, the reference point may remain unchanged, but it is still a scattered set. The difference is that every point (the actual transaction price) of this decentralization is unstable, and only the equilibrium value is stable

But in the value concentration of virtual currency, every point may be stable, on the contrary, the rational equilibrium value may be unstable. Reflecting on the monetary decision mechanism, the central bank is the personified representative of a fixed reference point of rational value, while the virtual money market (such as stock market and game money market) is determined by forces other than the central bank

It is in this sense that some people in economics call the stock market virtual money market and the economy formed by stock market and derivative financial market virtual economy. The essence of virtual economy is information economy with indivial as the center
