When it comes to gambling sites, I believe it's not the ideal platform for providing KYC information. However, as gamblers, we are obligated to comply with it if we want to enjoy the experience.
Actually, KYC is typically associated with fiat casinos, which is one of the reasons why crypto casinos became popular in the first place. They offered the appeal of anonymous gambling without the need for KYC. However, with the introduction of regulations, crypto casinos that are now regulated are required to implement KYC procedures for their clients. As enthusiasts of crypto casinos, we have to adapt to this new system since falling in love with crypto casinos means accepting the changes brought about by regulation.
It is difficult when it comes to how to do when a casino asks for identification or KYC, I very much agree when you say that KYC is for trustee casinos, there is no way it is a way to control who enters and who is in this activity style, but when it comes to online casinos and crypto they should not ask for KYC identification, if governments force it or something like that they should have the clear conviction that it should not be done, but no casino goes against governments, nor against the organizations that force this, firstly because they are closed and secondly they lose the licenses that I imagine are quite expensive, so I don't see casinos that really support technology, we as players have no choice but to play because casinos without kyc are few.
