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 we cannot really say that since we don't know more deeper about their situation but we cannot disclose that they can't afford to buy bitcoins as they still have works and businesses so for sure they can afford to buy at any amount they can spend with it. And since there's a news spreading about Cuba is thinking about legalizing bitcoin then for sure their government is now looking for possibilities and how they can get benefit for adopting it, maybe in next following months we can see their decision so let see what will happen to it as for sure they are now monitoring on the progress of El Salvador after they accept bitcoin as their Legal tender.
