Betcoin.ag or any other casino won't change their KYC verification related rules just for you. Different casinos have different systems for KYC verification. I can see why you are worried about the KYC verification requirement during withdrawal. At the same time, I'm wondering why are you so desperate to play at Betcoin.ag! There are many casinos where you can complete the verification before making any deposit. You should choose those platforms instead of forcing a casino to change their rules.
