Honestly, I like it when a crypto casino has sports book -snip-
test how fast withdrawal can be processed.
Yeah I also check beforehand if casino has any sportsbook with decent odds.
And I completely agree with you regarding 24/7 live support.
If you run into an issue and support tell you to send an email, only to keep you waiting for 24 hours then this is nonsense.
No matter how beautiful the casino is, what good is that to me?
And fast withdrawals aren't any luxury anymore, they’re standard requirement.
In fact, for gamblers, it is simple; they will trust a casino that pays winnings instantly. There is no need for KYC verification drama to claim winnings.
Yeah, all casino accept deposit smoothly enough. But the moment you try to withdraw your winning, KYC drama begins!
Show your face, turn right, turn left, blink your eye, provide electricity bill, and who knows what else! At that time it seems like I haven’t come here to play, but rather to open bank account.

I only trust those site that offer instant payout and don't hold players up with nonsense issues or unnecessary KYC hurdle during withdrawal.
