Do you think that this was intentional? Maybe to find reasons why they can't process your withdrawal? I think about the same too, but what about online casinos will enough credibility already? I mean very popular online casinos.
You know what about this kyc verification of a thing, it's only online this kyc is seeing like a way someone pass through an institution or like someone looking for admission in MIT, you know it's difficult right but it's very rare to see a physical casino that does this kyc of a thing but online has made things complicated as of you are going to do some evils to them, though having multiple accounts protection and money laundering preventions is been prevented by kyc but it's now too much of asking.
If you simply want to avoid all this kyc of a thing, as soon as you register your account, the next thing should be kyc verification and once you are verified, you can deposit money. Don't dwell on the instance they don't ask and you depend on that because later or sooner they will ask you for KYC verification, it's even possible that by the time you win a large sum of money and you try to verify your kyc, it might be rejected or ask for additional information that are not necessary, avoid casino problems the earlier the better.
