Maybe the best thing to do is to try the casino first, first enter a small amount to match it and through this you will find out what the casino platform has, from features, gimmicks, bonuses, withdrawals, deposits bonuses, and above all the TOS that it has.
At least in this way you can decide if you will continue playing because it is legitimate or not, then you will also know if it is centralized or decentralized, it's that simple and you know yourself what you want my Is kyc or not what you want?
