The wealthy left the country? lol you clearly haven't visited those countries, there are a lot of rich people (and not so rich too) that still love living there because is way easier than following the law in other countries, there is no cheaper country in the whole American continent to have an everyday party lifestyle than those countries (cheap good sex, cheap alcohol, no need to follow rules and cheap lands so you can have your own oasis)
It's only the middle class who need to use cryptos because they don't have access to the financial services those in power have. Plus the reason cryptos are getting popular is not just because "get rich quick" but because is easier to use and because both countries handle a lot of remittances
I lived a lot of years in both countries, if you're going to tell me something at least try to say something that is true
