That being said, it was obvious that El Salvador will face many obstacles from these kind of institutions and big countries because they adopted bitcoin as legal tender. Accepting what others are fighting against means your standing against them. The IMF wants El Salvador to tighten bitcoin laws and be more controlling, lol. I mean, that's exactly what most countries want, to restrict bitcoin in a way that they have control of everything. This alone goes against what bitcoin stands against.
It is certain and will happen, but the President of El Salvador is smart and has also reviewed this before making his decision. It could be the ultimate dream of the leader of El Salvador if perhaps they will pay off all their debts with the IMF or others with the help of BTC investment instruments.
I think the IMF is only talking about the economic inequality that is currently widening and trying to provide recommendations in addressing potential fiscal and financial stability issues that come from the Bitcoin initiative as I read in the news from the OP's post link.
However, one thing that is most needed now is how all countries will be able to pay off their debts from various sources including the IMF whose interest continues to accumulate over time, including El Salvador.
