If we want to withdraw a large amount, there is a way to avoid a KYC, namely by withdrawing gradually with a smaller amount, but we make several withdrawals until all the money we want can be withdrawn.
Maybe for now we can use some casinos that don't require KYC but maybe in the future more and more casinos will impose KYC requirements and we should be able to accept them.
Making gradual withdrawals may be the best advice to avoid KYC requests if you have high funds above $100k (depending on the withdrawal limits of each casino), but if you have funds below $100k maybe you can withdraw everything at once from the gambling account. Recently many top casinos have asked for KYC for the first withdrawal without withdrawal limits, now many gamblers have done KYC verification at top casinos because other casinos do not guarantee protection of user data security and fair play.
