I have played at a couple of crypto sportbooks and only Stake and  Sportsbet have stood out for me. Apart from a superior user experience, They have been straightforward with the promotions and has handled any issues raised by other community members pretty well. I started out at Sportsbet.io but I've been playing more at Stake of late and I haven't had any problems with my bets, the markets available or even with withdrawals.

There are other sportbooks here on the forum and people say they're trustworthy but I only have experience playing at stake or SB.
