The fact El Salvador accepted Bitcoin as a legal currency does not mean that other government across the world will accept it someday. The reality is that , the government will keep fighting bitcoin with all market strategy and strick regulations.
Reasons why they will keep fighting is not about the prosperity of the people majorly but about power and authority to control people. This is why they prefer the centralized system in order to keep the people poor so that they can run to their feet for daily bread, seek shelter and wait for other provision.
We all know that through Bitcoin, every one will be there own boss. No control or submission to any authority over your own belonging or money, the life threatening taxes will be done away with.
But as of now, no matter how popular Bitcoin becomes, it will keep facing the wrath of the angry government who need to keep people poor.
More also, before bitcoin will become used by everyone across the world as means of payment, most users hear must have grown white Bear,
We already know that the majority of the governments will fight bitcoin with everything they have or at least they will try to make it submit to them, and we are seeing this with all the policies that are being implemented against centralized services like exchanges and casinos, but at the end they will fail as they cannot change the nature of bitcoin and because the economic system they have put in place only benefits them and the rich, leaving the middle class and the poor behind.
