Hmmm it seems like what I've been seeing about sportsbet.io is true since you didn't mention them on your list. I have been seeing some people that complained that sportsbet.io never paid them their huge winnings, instead they will block (I only saw a few people that said this). But a lot of review sites I see when I research on Google always mention Sportsbet as one of the best betting sites. Most of them even put them as the number one, while CloudBet is then placed at number two position.
I would suggest you to stay away from sportsbet because they have some issues. Although they do pay you but they hold your amount in case of larger wins and this makes them a bit fishy. This has been told by few players who actually play at sportsbet. You can use clouldbet or onehash for sports betting.
Oh thanks for sharing this, I always thought sports bet had a good reputation, this is a dent on their image and I hope they correct it soon, I was actually thinking of placing my bet on the site, its good am on the forum to read this.
Getting a trusted sites these days has become quite difficult, who would have thought sport bet of all site would be involved in this mess, I always implore my friends to stay active on this site because they are so many information we gain here that it would be hard to get outside the forum and even.
