Some will probably disagree, but I think more and more casinos are implementing KYC, even for small withdrawals and even if there is no suspicious activity on your account. I can understand that some want to stay anonymous but I don't really have a problem doing it, if it is a legit casino. Similar as Bitiniy, I have been asked to do KYC on several casinos, for small withdrawals.
Agree on this. Some casino dont consider anymore the amount of withdrawal or the size of bank roll to implement KYC. Theres a lot of new casino that implement KYC before a user can withdraw their money or before they do their first deposit. I believe due to the regulatory compliance that pushing casino to be more aggressive when it comes on collecting data from their customer as part of the AML policy and anti-cheat system of the casino.
