the thread caught my attention because I thought there are many sites without KYC, or They don't require that identification to operate, but I see that now getting a place like this is almost impossible
You are totally right.
It's almost impossible to find a crypto casino or a centralized service that will never ask you to verify your identity at some point even if they claim they won't.
Just recently, a new member complained on the scam accusation board about a casino for asking him to pass kyc after winning (obviously) although they have a huge banner on their main page stating that they are a kyc-free casino!
