According to Zero Financial News, economist Zhu Jiaming said in an interview that there will be two major types of currencies in the future: one is the legal currency of the government, and it can be divided into non-digital and digital legal currency. The fiat money will not all be converted into a digital type, but will be a coexistence state; the second is the illegal determination of the digital currency, and the centralization of the illegal fixed digital currency and the decentralized illegal digital currency. In addition, it believes that the encrypted digital currency cycle has little to do with the current economic cycle. The main reason is that the size of the encrypted digital currency is still small. However, it does not mean that the future has no impact on the economic cycle.
