People are shifting to Cryptocurrency because of the anonymity it provided and much more in casinos, gamblers do not want to get exposed so they are making a shift, that is why Cryptocurrency casinos are beating fiat-based casinos so obviously my choice is no KYC casino, there's always an exception to the rules of non KYC like checking one user who they suspected of abusers and checking the legality of one's player, these two are acceptable, other than that like a registering on the casino that asked a KYC is a big no.
