So far, there is no concrete evidence that El Salvador is using borrowed money to buy bitcoin. It's all speculation, because if there was evidence, the IMF would immediately stop the loan because they were in serious violation of the loan agreement.
El Salvador will have enough money to buy bitcoin with a 1 bitcoin per day strategy because this is not a large amount for a government. But the problem is that the IMF sets an additional condition that Public sector funds cannot be used to buy bitcoin. If El Salvador doesn't use Public sector funds, what money does it use to buy?
El Salvador is a small nation in economic size and changes in that nation are not big enough for creating massive effects at global scale. Years ago in a past market cycle, this nation played important role to hype Bitcoin community and market with Bitcoin Legal Tender then Bitcoin Beach City months later. Their government have been continuing their DCA in Bitcoin since that Bitcoin Legal Tender day and other nations have been following El Salvador's Bitcoin DCA strategy too.
Diferent nations have very different conditions but El Salvador and their national success with Bitcoin DCA over years, together with another bigger successful story from Strategy (formely MicroStrategy) actually contributed considerably to Bitcoin adoption worldwide.
IMF can have its impact on El Salvador but this foundation can not impact all nations globally so don't worry too much about IMF.
