It has given some power back to Nayib Bukele on the negotiation table because he is doing what the World Bank and the IMF does not want. These institutions run by the rules want the small minnows to use only their currency because they want control. This is not anymore wholly possible with bitcoin as legal tender because the IMF and the World Bank cannot control bitcoin.
I don't know why you have been repeating the exact same thing, even when it is incorrect and when more than one member has tried to explain things to you. How does making BTC a legal tender give El Salvador power in the negotiation table, they accept and pay back loans in the U.S dollars and not in BTC.
Surely the IMF and the World Bank cannot control BTC, but that is not what we are talking about, El Salvador isn't going to be offered loans in BTC, but in the U.S dollars, so what's really your point?
