Bitcoin is the first cryptocurrency and have remained the most popular and accepted cryptocurrency in the world. I don't see the possibility of any new cryptocurrency beating that record, not even now that many governments and institutions are contemplating creating Bitcoin reserve, that simply shows that Bitcoin is approaching the level of gold in terms of acceptance.
Bitcoin has made a name for itself. The government has tried to control it. Some entities have also made their moves, and since the government can't climb down totally on control, what they are doing now is to acquire as much bitcoin as they can, holding much of it to threaten market control.
Policies are also another indirect way they have tried to decide what's what for whom in terms of deciding how their people spend their coin. As long as you hold your coin in your noncustodial wallet, you are free from their central control. Bitcoin is not decentralized if you keep it on a custodial service.
