I think many crypto casinos have somewhere in their terms that they ask KYC in case of something suspicious or when winning a large sum, but many don't require it yet to play on their site.
This is very true, the reason is very simple, now casinos are protecting themselves from money laundering, because it is very easy to put money into a casino and then withdraw it to any address, where the bridge is the casino to take liquidity from it. , if there is KYC things change, and later if it is a whale-style player like the ones on stake.com it is different, because the millionaire profits can be withdrawn instantly as they have shown in their thread, these things also go into special cases that every casino should have.
