The governments can't control Bitcoin because it is decentralized. It wasn't made in favour of a centralized system where one person or authority can have full power and control over its transaction. The farthest the governments can go is to impose regulations on Bitcoin transactions especially on the exchange sites.
Governments can stop the acceptance of cryptos, they can stop the conversion of fiat into cryptos and vice versa and lot more things they can do even if it is decentralized but they can't do anything to stop a bitcoin transaction but literally no one will use it if it doesn't have any value.
