Let's be careful
All of these countries are poor and being hammered by a weak dollar. This could get messy if the US protects usd hegemony
Careful where?
Bitcoin is decentralized so even the US will get into it, they can't control Bitcoin.
The only problem here if a country like Paraguay will get into local business owners that are accepting Bitcoin and they will enforce it not to accept Bitcoin for payments, that's more the real deal.
