1. Is there a visible licence and who holds it?
Every operator worth considering has a licence number displayed in the footer. Verify the number on the regulator's site (Curaçao GCB, Anjouan eGaming, SIGAP, Coljuegos, MGA). 'Licensed offshore' without a specific number is a red flag. The owning entity should also be named — a Curaçao licence held by 'XYZ Ltd registered in Curaçao' with no further detail is weaker than one held by a named entity with traceable public filings.
2. How long has the operator been running?
Crypto casinos fold frequently. Operators under 18 months have no dispute history to read. Operators at 2-3 years have useful signal. Operators at 5+ years (Cloudbet, Stake, BC.Game, Bitcasino) have enough track record to properly judge. Use operator age as a direct trust input — prefer older unless you have specific reason to try newer.
3. What does the public complaint pattern look like?
AskGamblers' complaint database is the single most useful public source. Every major crypto casino has a profile with historical complaints. Read the pattern — payouts-denied versus verification-friction complaints are very different categories. Payout denial is a red flag. Verification friction is universal above certain thresholds. Resolution rate and average response time both matter.
4. Are the welcome bonus terms survivable?
Welcome match under 40× wagering. Max-bet rule above $2 (or use banker-strategy baccarat which contributes 10% anyway). Max-win cap above 5× the bonus. Game weighting tables visible. If the terms violate any of these, treat the bonus as loss-leader marketing rather than real value.
5. Is the withdrawal behaviour documented?
A clean operator tells you explicitly: minimum withdrawal, withdrawal fee (at-cost or marked up), expected processing time, KYC trigger thresholds. Vagueness on any of these is a yellow flag. The worst operators are silent on timing and processing until you hit withdraw and discover the reality.
6. Which chains does it actually support natively?
'Accepts crypto' is meaningless. The concrete question is which specific chains have first-class deposit and withdrawal rails. An operator that nominally accepts ETH but forces L1 mainnet is charging you $15 per move. An operator that supports Lightning BTC, Solana and TRON has cheap rails. Breadth matters less than quality of the supported chains.
7. What's the KYC posture at signup and at withdrawal?
No-KYC at signup is the category default among offshore operators. No-KYC at withdrawal depends on size. Some operators document specific trigger thresholds (Jackbit is near the transparent end); most don't. The complaint database tells you how the operator behaves when KYC fires — friction-but-resolves versus indefinite-freeze.
8. How does the live-chat support feel?
Open a live chat session before you deposit. Ask a real question. Response time, depth of answer, willingness to link to terms — all tell you what support will be like if something goes wrong. If they can't answer basic questions at 11pm UTC, they'll be worse when you have a problem.
9. Does the operator have a responsible gambling page?
Real ones have deposit limits, session timeouts, self-exclusion tools, and links to helplines. Fake ones have a boilerplate paragraph. This is a compliance requirement for any regulated operator and a quality signal for unregulated ones — if they take responsible gambling seriously, they probably take other things seriously too.
10. Are game providers named and verifiable?
A reputable operator names its providers: Pragmatic Play, Hacksaw, Nolimit City, Evolution Gaming, etc. The games come from those studios with certified RTPs. A lobby full of games with no provider attribution is a lobby full of games you cannot verify — avoid.
11. What happens to your data?
Privacy policy should be specific: what data is collected, who it's shared with, how long it's retained, your rights under GDPR if you're in the EU. A generic placeholder privacy policy is a sign the operator isn't taking this seriously. Compliance cost-cutters on privacy are usually cost-cutters everywhere.
12. Can you leave cleanly?
Before you sign up, know how to close the account. Self-exclusion tools, account closure requests, data deletion requests. Operators that make it easy to leave are operators that don't need to trap you. Operators that bury the close-account option behind three support tickets tell you something about their business model.
