That's right, almost all casinos already require KYC and this is something that will continue to be required, and the terms and conditions that will be made will be to see how authentic the person is and if they did not commit fraud with their documents or something, I think that is one of the reasons why KYC is required when a withdrawal will be made, which I find sometimes a bit annoying, but when looking at it from a point of view focused on player security, it is good, because If you enter your account, they hack it and make withdrawals only with the input data, it is something that can happen, it has happened to me that one day they did it because they did not have a 2FA security layer.
KYC is a protection for both the casino and its users. No one will cheat after passing KYC, since the casino knows his name. At the same time, regulation and KYC protect the players. If the casino deceives the player, then the player can complain to the regulator, specifying his personal data and the regulator can check everything whether the player is actually right.
