I bet OP can't give one reputable casino that does not ask for KYC, reputation, and compliance go together, a casino cannot be reputable without compliance, I don't think people will patronize an establishment online or offline with being regulated or licensed especially if big money is involved, it is illegal to run a project online which ask people to deposit so if OP is naive not to play in a casino that asks for KYC it's his own choice and his choice is not only risky but very limited.
I don't know why any time I play in a gambling which does not require kyc, I will feel that anything can happen to the company or my money. I will feel insecure and will play with small money and little wager in order not to win big. No matter how the company says they don't kyc, you must do kyc if you win big or even the company will run away with your money or victimise you. When they say No kyc, have it at the back of your mind that there's some form of kyc at the end.
Maybe you have already some experience about those site that does not ask for KYC but all of a sudden when you wanted to withdraw they will ask?
and also many times that we have seen this issue here ,. that players made post about they are suddenly being required of KYC .
so legit casino nowadays ask KYC right away upon creating of account.
