El Salvador probably wanted to keep their image as a bitcoin friendly country. Not only do they want to appear friendly to bitcoin, it seems like they want to be a country known for having a lot of bitcoin and possibly get investors in their country. I have seen some people doubt IMF's reports but what do you think? It makes sense if bitcoin has become El Salvador's political move.
El Salvador is a Bitcoin-friendly country, they have been holding Bitcoin for a long time. So I never believe that the IMF, this lending institution, will suddenly make false comments about El Salvador, the IMF will completely deny the comments made by Nayib Bukele. Because before this, the IMF, this lending institution, had issued such warnings and restrictions on Bitcoin holding, but in no way did the government of El Salvador, Nayib Bukele, care about their restrictions.
So I do not think this current ban is necessary, because the government of El Salvador will continue to hold Bitcoin with its own plan and will move towards development by keeping its country under proper control.
