If they are not going to add a sportsbook soon, then no-KYC is very much possible. If I am not wrong, the players cannot abuse the slots. As for bonuses, the casino can have its own algorithm to detect bonus abuse and find alternative accounts. So, if they want to remain no-KYC, it is possible. If they do not get a license, asking for KYC is not legal for them since the business is not legal either.

There are dozens of No-KYC casinos, but almost all of them are under rated unknown casinos. I don't remember seeing any big casinos that do not ask for KYC. Duckdice is a big one, not sure if they ask for KYC.
