Many talk about developing a national cryptocurrency. bu I think governments will not use cryptocurrency until they find out how to control it..
By and large, no one needs the government to use Bitcoin or another cryptocurrency. To begin with, it will be enough for the state to allow at the official level to store, buy, sell, mine, change, etc. That is, cryptocurrency must have an official status. just like we have it in the US
An official status for cryptocurrencies can only appear (in my opinion) when the state levies all cryptocurrency transactions with taxes, adds full identification of citizens and makes an exchange only through official, state exchangers.
