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.
The sites listed are not the only trusted sites and we all know that. The OP that listed that probably has reasons why he chose those sites and its good all the same, but its not enough for you to assume sportsbet is not real or because of mere lies that might have been shared by some few problematic folks out there.
Sportbet as a matter of fact is one of the most reliable casino sites I have seen and am glad its even on Google review for anyone that is interested to check out. Sport betting is really a big business today and being watched by millions of people from different parts of the world.
