The T&C's would probably always return that the casino will confiscate funds in the worst case scenario.
honestly I can't understand this attitude of a casino withholding customer funds because they refused to do KYC, KYC's goal is to fight money laundering but if the casino says that people shouldn't deposit and withdraw without at least playing until they reach 50% or 70% of the amount they deposited then any possibility of someone stealing money and depositing it in that casino to do money laundering is impossible, so why would the casino retain people's money because it didn't pass KCY? my conclusion is that many casinos are using KYC and TOS to retain and steal customers' money.
I think the OP should get in touch with the support of each casino and ask how long it will take for the KYC to be approved, with that we would have an idea of how long each casino takes to approve KYC and in case we hear that someone complained that it was too long more time waiting for KYC while here in the OP it is that the casino does KYC quickly so people would already be cautious when they use this casino, for me having this data is something very relevant, because many casinos lie a lot especially in this KYC issue
In a relevant problem when casinos are suspicious or suspend accounts or block, it is very difficult for the player in question to have reasons to win those cases,they would have to open up a lot to be able to accept that the casino was wrong, but I start from a premise, if the casino Makes a Mistake, the casino quickly assumes and removes the player's balance, but if the player makes a mistake?I have not seen cases where the casino makes returns because there was an error and the Player asked for a lot of money and it was returned to him, I have not seen that, and I think that Something like that has not happened.
