In fact, you have to look at this in different ways. For example, you should ask why some governments have simplified the Bitcoin Mining Terms? And why do they help miners? And why have some of these governments themselves begun to bite the mine?
bitcoin is made by the government, I think it can happen, but the nature and purpose of crypto currency will certainly change, but in my opinion it will not make crypto currency but the government will adopt the economic system to progress a more developed economy
