I think dollarized nations are prime candidates for orange pilling. They don't control their currency anyway and realizing that they really have nothing to lose by adding decentralized sound money as legal tender makes a lot of sense.

Generally, I think the playbook for Bitcoin as legal tender is being written right in front of our eyes in El Salvador right now. If it is generally considered to be a success a year or two down the line I think the dominoes will really start to fall.
