But as we know this is not possible here, so by gambling on the first casino they find that gives them the bonuses they are looking for, they expose themselves to becoming a victim of scammers, and when it happens they are surprised they do not have anywhere near the protection they expected to have, and it surprises them even further when they come to the forum and they are told their expectations were out of place.
Not necessarily true. Crypto casinos are not much different from fiat casinos.
If you play at a licensed and trusted crypto casino then you don't have to worry about losing your money and not being able to sue them if they scam you. It's all about how reliable the casino is and where it got its license from. Some crypto casinos are even safer than many fiat casinos.
