Would you rather play in a casino where you win a lot and big ones too but has strict KYC implementation and is a headache to actually cash out from or play in a casino with no KYC, totally private and secure but doesn’t let you win a lot?
I know that in casinos, there’s not much difference between rates of winning because it’s random but hypothetically which one is more important for you? Profit or Privacy?
I would be more concerned about the aspect of fair play, especially in a totally private non-kyc casino, since those are unregulated and can therefore be as scammy as they want. If KYC is a hassle then just do it beforehand and not worry about whether or not they will let you pass it later when you decide to finally cash out your winnings.
A reputable casino is far more important than some shady one that operates in a grey area or with no regulations or oversight at all.
