I lost money most in fiat casinos because I have known them since many years ago unlike crypto casinos that I know about 5 years ago. As long as you register on a casino and you started gambling, you are most likely to lose because all the games are most in favour of the casinos and not gamblers. In fact, most games in crypto casinos are in fiat casinos except just few. They are just the same if comparing which one is riskier.
I don't fully agree with you. The fact that you lost more at FIAT casinos doesn't mean cryptocurrency casinos pay out more; it must have been just bad luck.
I could say the opposite—I've won more at FIAT casinos—but that would still be misleading.
Regulated casinos don't scam users; rather, they try to retain their customers. If you play at crypto casinos, we have a wide variety of them here on the forum, and they're obviously reliable.
I think what @Charles-Tim said was that he has lost more money on fiat casinos because of the long duration he has used them. He lost less in crypto casinos, not because they are better but he just started using crypto platforms five years ago. This is also my experience since I am new to crypto casinos.
Any casino that is not fair will not last for a long time because gamblers will avoid it if they find out that they are un unfair. You are right majority of casinos that have a long time presence in the forum can gain my trust.
