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.
Days without KYC on centralized platforms will end soon. It is out of centralized platforms to control their policies on KYC and AML because they must obey government and regulation so that their platforms can legally operate without problems with governments. They must protect their companies first and customers will have two options that they don't like but have no choice left: staying and doing KYC or leaving and finding another platform to use.
Mostly, if it is a platform that is highly trusted and that user really like, he will do KYC to continue using his account.
