Fiat currency will not be replaced by encrypted currency, and the national government will launch its own digital currency.
Although cryptocurrency brings a lot of value benefits and freedom to people, its decentralization makes it impossible for the government to control it, and the use of cryptocurrency is detrimental to their own interests. And the price of cryptocurrency is unstable, and it is not yet fully applicable to daily transactions. Its anonymity is also not conducive to tracking the scope of transaction use, and it is easy to be used as a criminal method. Some countries also ban the use of bitcoin.
