IMF a technically west lobby that decides who should do what and what is right form of the money movement. In past they were in the business to serve the rich nations while giving loans to the poor. And the way they worked later they started funding the rogue nations in the middle eastern and created contractual terrorism for which we all are paying in a way. 

Same IMF now wants to ban the El Salvador from the bitcoin purchase and they won't be funding 120M deal for them and one of the requirement for that is making sure they don't hold bitcoin anymore. It feels like they serve the intentions of the western lobby on the crypto topic. 

As you can see more and more non US nations buying the bitcoin and holding them brings more power to the bitcoin. And things would improve from this point onwards. And this is the path that many of the nations are taking. Some are also taking loan from IMF for this. As sooner or later IMF funding would be coming in the light and then it would not matter with crypto taking over. 

In case of El salvador we can see they want to protect their wealth for the upcoming times. And they would be making sure to use the cryptos and the variety of the assets which would have some decent value and the funds in the pocket too. If everything goes well they can survive IMF in near future. So they dont have to bow down to those funds in near future. 

Most likely govt are going to be making use of other companies and investing into them to hold such assets. World does not have to bow down to USA and IMF and their policies and buying crypto for safety is a good direction.
