But I understand now that we have common opinion about the case of OP that he can’t claim his fund without undergoing KYC.
Each casino has its own rules and we must read them before playing in the casino and follow the rules because from the moment we make a deposit the money is now casino money and they can find a way to lock it if they want.
Is not the first time I have seen a casino confiscate the user money with the KYC argument, casinos are in their right to do it, but on the users' side doesn't feel fair at all.
