I have more trust in a site that requests KYC information when a player registers his account and before the first deposit is made, than a casino that asks for private details when it's time to withdraw money. The practice of not caring who the player is until he wins something significant is sometimes misused by crypto casinos. I would rather be told at the beginning: If you want to play here, you have to do KYC. That way I can either agree and do it, or find an alternative place to gamble.
