Not Cubans, they're a communist country so I don't think that they're going to benefit too much with bitcoin plus they wouldn't have any use of it if they have one because they probably rely on P2P and I am pretty sure that there's not a lot of people there that have money to buy their crypto.
Well there in that statement I support you, the only thing is that those who can gradually accumulate some BTC even if it is very little will do it, if those people have more than 60 years without money, I think that 3 years or 4 years saving from very little I'm sure they will.
Regarding the opportunities they have to obtain BTC, I think they will be the same as everyone has, the only thing is that in Cuba everything can be controlled even by the internet, and those who do not adapt to the conditions offered by the government I think they will be of Similarly punished, I think that in Cuba the use of VPN will grow a lot so that they can carry out BTC transactions and thus can overcome the prohibitions that the government has on them.
