What "KYC may be required" means at crypto casinos (and when it gets triggered)

Crypto casinos may require Know Your Customer (KYC) verification despite marketing as 'no KYC', triggering ID requests during withdrawals, with common triggers including larger withdrawals and unusual betting patterns. KYC requirements can cause delays of 6-72 hours or more. Users can reduce the chances of surprises by keeping withdrawals smaller and checking terms before playing.
