Definitely agree that crypto casinos should keep KYC to a minimum unless they suspect the player is a politically exposed person or perhaps their transactions appear to be money laundering related. It's usually quite obvious to the casino when users are attempting to launder ill-gotten funds, the players meet minimum requirements for deposit withdrawal (usually 1 or 2x wager of total deposit amount) and then immediately try to withdraw the majority of funds.
Gambling should be for entertainment and not a route for scammers to clean funds after all but I'm definitely pro no-kyc!
