So KYC is good or bad, acceptable or unacceptable, it depends on each person. It's just sometimes a business company does not have choice to request KYC on users because they have comply with local laws.
If you're a private person and don't want to disclose your personal information, you might take this KYC thing as bad. But there's still casinos that are not asking their gamblers to comply with KYC and you can play anonymously.
But to choose a casino that doesn't enforce KYC, gamblers still have to be careful and read all the casino reviews because there were several cases where at first the casino said that they didn't have KYC, but one day the gambler got a big win, the casino asked KYC for withdrawal requirements and this case a lot has happened.
Maybe gamblers can first look at all non KYC casinos and consider properly to decide which casino to use so that cases like the ones I mentioned don't happen.
In this forum, there are several non KYC casinos that gamblers can make references to, so gamblers only have to do research and register there.
