100,000 Cubans out of a total population of 11 million are using crypto currncies for payment, according to a 2 May 2022 NBC report. Primarily, they are doing that to bypass financial sanctions imposed on their state.
I also suspect some of them do that to bypass numerous controls their highly oppressive Communist state imposes on them.
This is a very interesting tidbit. I wonder if, among other things, crypto is going to hasten the collapse of various top-down oppressive regimes around the world.
