They were asked to to scaled down their involvement on bitcoin which they have, but asking a soverign country not to buy an asset with its money seems so shady.
It is truly shady but you know that the world organizations like this, including world bank, United nations are heavily influenced by the United States.
Also the namt IMF is not what they should be called, they supposed to be called IFF which mean International Fiat Funds. And the dominant fiat is United States dollars.
Even Bukele has mentioned making it a bit different, like not forcing anyone to accept bitcoin if they do not want to has become law again. Plus, El Salvador's plan to make bitcoin common, became not a successful attempt. Because less than 10% of people have any money in their crypto wallets, so it is not really accepted all that much by the public.
What IMF is simply showing is that we are not really shocked about Salvador ending up with IMF loan since they needed it, and IMF put up some collateral needs for it. Why would IMF give out loans to a country that doesn't use it and instead uses their money? IMF could have easily said "go sell your bitcoins if you want money, we are not giving any" too, it's their money, if you want their money, you follow their rules.
