IMF will stop pushing El Salvador when other countries also buy bitcoin and make it public. Then the community will be bigger and the IMF will not be fight against everyone. That is why Bukele is strong and keeps going, he knows exactly whats coming. That is exactly what Bitcoin need when others join in. If El Salvador lose this fight, then other countries have a reason “not to buy”, or not to publish it. I am sure that many others have already bought bitcoin.
Will the IMF ever say anything negative about the US having BTC strategic reserves or Pakistan planning to do the same? Of course, this will not be the case because they can blackmail only those small countries that have no choice but to submit and accept all the conditions that have been set for them.
I honestly don't see what kind of battle El Salvador can lose, unless someone still believes that Bitcoin can save them from decades of corruption and economic mismanagement. On the other hand, any country that decides to invest in Bitcoin in any way should do so in the most private way - because otherwise they are not doing themselves any favors if the price rises due to this news.
