Mother currency is a currency that can generate new virtual currency. This currency can't be traded and bought in the market, it is only responsible for generating new currency. The mother currency is like a bitcoin mining machine. Only when you have a bitcoin mining machine can you mine and get bitcoin. Only by buying mother coins can more new coins be created.

This kind of virtual currency is mainly subscription currency and pyramid scheme currency. There are some subscription coins. In order to attract more players to enter, players who enter often buy mother coins and then automatically generate new ones. Players who buy them will also try to promote the counterfeit money. This is especially true for pyramid schemes.

Of course, the same is true of digital currency Fuyuan Coin, which has recently surfaced in the jewelry industry. In order not to disturb the normal order of the market, the new currency generated by the mother currency will have a certain sealing period, during which the new currency cannot be bought or sold, but is frozen.
