I think one of the big advantages for crypto casinos are that they offer games with a much lower minimum bet, betting with one satoshi or the smallest micro unit of a cheaper crypto currency, makes betting on online casinos affordable for everyone.
It is like this and one of the best is no one will know how much you paid and in crypto currency no one can trace or see your money, crypto gambling gives safety and reliability to users, it remains security between sender and receiver but paying with fiat will be dangerous as so many people come to casinos only to rob the winners.
