But I don't really like casinos stressing someone at the time of withdrawing his win with KYC. KYC would done before the withdrawal so things will be easy for the gambler to do.
If I'll be asked about this, I don't think I can do this immediately because there is no street sign on the place where I live but I need to travel in the town first lol. Usually, KYC is asked if the withdrawal amount is huge. I think that is for them to know that it wasn't a laundered money and also to know that the original owner still controls the account. There are still gambling sites who can ask a KYC at the start or even if the withdrawn money is only small.
In particular, I think that things that have to do with kyc are quite demanding at present, I have only taken a kyc selfie on Binance, and it seemed somewhat tedious to me even though it took only 5-5 seconds to do it, but it is something I did not like it because I wanted to verify if it was really me, although it is a security issue but for a casino it may be applicable if it is a person who handles a lot of money, like whales, and since it is a lot of money, it is a way to protect to the player, then it's not such a bad thing, doing a kyc on the street if it's something that's not very good or recommended, I'd rather wait a bit and do the kyc in a safe place.
