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 actually a great advantage because crypt gambling has given people like me the opportunity to play.
Fiat gambling is usually more expensive and most times the fear of committing such amount to try since there will be no 100 percent chances of getting it back, but with crypto its always like a token and it always look easy to spare and also to participate.
I really like crypto gambling and those little satoshi or 0.002 BTCs have brought me back a whole lot of money.
