Bitcoin is not under anyone's control, if someone bans someone it would be wrong, Bitcoin is not controlled by any government. So if someone bans El Salvador, then they are on the wrong track. Nayib Bukele has taken various steps to educate the people of his country about Bitcoin, here Nayib Bukele is a great person. I think this could be a kind of conspiracy, because no one wants any country to get ahead of them. The way El Salvador has started accumulating Bitcoin, they will go far in the future economically, some countries will not be able to accept it, so maybe they have been banned. However, such a ban cannot be feared, so it is wise to move forward according to the plan. The decision that Nayib Bukele has taken should be praised.
IMF wouldn't get rid of the idea of letting BTC thrive -as long they have the influence to change or halt people's ideas and ways, other from the traditional ones.
