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,
You don't have to sound more like any one that get in terms with Bitcoin automatically becomes rich, don't be in a hurry to forget that Bitcoin is not a quick and get rich scheme, there are those who might not be that patient enough to ripe the potential that Bitcoin holds, which has nothing so with the government fighting against Bitcoin as a decentralized asset class, there is no guarantee that anyone who gets involved with Bitcoin will become rich. However, Bitcoin is a freedom currency and not just to be seen as a means of payment, which has to do with have the total control over your money, it offers privacy of which the government are not comfortable with the reason why they are most fighting it, my point is even if Bitcoin is not generally accepted as a means of payment which is not the main purpose for it's invention, it will still stand for what it stands for.
