1. License and corporate registration
Every reputable operator names the legal entity behind the brand and links to its license number in the footer. Curaçao is the most common jurisdiction for crypto casinos. Anjouan, Costa Rica, and Kahnawake also appear. A site with no visible license isn't necessarily a scam — but it removes your only formal recourse if a withdrawal is refused. Cross-check the license number on the regulator's public register.
2. Withdrawal track record
Speed of withdrawals is the single best proxy for operator health. A casino that pays in minutes and publishes its average payout time is signalling that it has the float and the will to honor wins. A casino that processes deposits instantly but routinely takes 3–7 days to release withdrawals is solving its own cashflow at your expense.
3. Game catalog and providers
Look for slot games from established studios — NetEnt, Microgaming, Pragmatic Play, Play'n GO, Evolution (live dealer). These providers license their software and the casino can't tamper with the math. Pure in-house catalogs are not automatically bad but require provably-fair verification.
4. KYC policy
Some casinos accept anonymous play up to a threshold (often 2 BTC or equivalent of cumulative winnings) then require ID. Others demand KYC on first withdrawal. Neither is wrong; what matters is that the policy is published BEFORE you deposit, not surprise-applied after you try to withdraw.
5. Bonus terms
Always read wagering requirements, max-bet-during-bonus rules, game restrictions, and time limits. A 'huge' 500% bonus with 60x wagering on slots only is usually worse than a smaller 100% bonus with 30x wagering and broad game eligibility. See our 'Casino bonus math' guide for the underlying EV calculation.
6. Support responsiveness
Open a live chat before depositing and ask a real question (deposit minimums, withdrawal time for your chosen coin, bonus terms on a specific promo). A response time over 5 minutes for a basic question predicts what happens when you need to dispute a withdrawal.
7. Reputation and longevity
Operators that have been live and paying for 3+ years are unlikely to have been a scam from day one. Search the brand name plus 'rogue' or 'no pay' on independent forums (AskGamblers, CasinoMeister, Reddit's r/onlinegambling). Heavily upvoted recent complaints are a stop sign.
