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.
