I seem to believe that a government accepts and validates cryptocurrency in their country for some reason. It could be true if:
If my idea proves to be correct, will the government of the country accept it?
1. Will the government of a country ever want their banking sector to be abolished?
2. How will the government collect taxes from the people?
3. If the government can't keep track of people's legitimate money, won't corruption increase?
They must have the aim of legalizing it whether they are really aware of the technology, don't want to miss the chance to join the party, or even hidden goal for the further and later regulation? I think taxes are very reliable to be considered because they may also have been considering about this.
Maybe the government needs a process that will validate to accept cryptocurrency because what if a country legalizes cryptocurrency it must be considered because of how the blockchain technology works.
In legalizing, of course, the government must legalize it, but this does not interfere with legal currency because it is evident in reality, but still in the collection of tax fees, it must be discussed again, what if the money is stored in crypto the government must also be able to control what they control.
