Most crypto sportsbooks have a decent reputation so there's no need to worry about it and those sportsbooks with bad reputation or bad history are very easy to avoid.
Agreed with you on this point but as newbie some gamblers might get themselves distracted to those less reputed and fake casinos if they don't go for the reviews and check only high odds so i was referring to that part.You could make decent profits from the legit sports book provider that are available in the market to crypto users and easily indentify them as said by you.
