That's right, it's very simple to gamble, but what made it really popular is people now can gamble anonymously as we are in the crypto space. Although I must say that some gambling sites are already strict now when it comes to KYC requirements but everything starts with anonymous gambling.

I think that at the early stages the anonymity this market brought was something that gamblers found refreshing as they no longer needed to pass complicated KYC procedures to be paid, however as time has passed it is more difficult to get this level of privacy but even then compared to other online casinos I think cryptocurrency casinos are still doing the best job they can to not ask for KYC details unless it is is absolutely necessary, since they still want to protect the privacy of their users to the best of their ability....
That is the main attraction I would say. Being able to gamble anonymously along with lower commissions or lower HE than fiat casinos, which ends up providing a better user experience. The OP was wondering about reliability, and, despite the fact that scams abound in the crypto world, a crypto casino all it needs is to attract customers. The moment customers come through the door (virtually) on a consistent basis, casinos are money making machines and don't need to tweak the algorithm or anything, as they are going to give a better experience and a better return to users than fiat casinos.
