I'm talking about casinos that accept only cryptocurrencies. (No fiat money)
A lot of crypto casinos are legal and registered entity. They run by a proper legal entity name and licensed to their originating country.
However, it depends on the lecal law to determine if a person from a certain nationality can play crypto casinos or not. Usually online casinos are open to the world, but the player needs to identify their own legal clearences.
