Venezuela is one country where BTC use could really be pushed. It's a country where people really are in need of an alternative to fiat. I don't think that Maduro will allow it though, he'll push Petro if he has to to replace Bolivars.
Madro in theory is now less negative on all types of crypto as it allows them for an alternative source now sanctions via dollar is a real problem for them. Why they cant just use the soviet Russian rouble as a proxy in their economy I dont quite understand but the fact Russia is also under sanctions is probably a large part of it.
1 single ATM 9 years after it was required to stem inflation, is far too little too late and sadly cant turn around the titanic failure that is this OPEC nations lament
