Number One Pick
Cloudbet.
This is my new favorite. Unique and custom designed site that is very easy to use. Huge list of sports that you can bet on with bitcoins. Basketball (men and womens), Soccer, Tennis, Golf, Football, Ice Hockey, Cricket, Mixed Martial Arts (my favorite), and much more.
Not just sports though. Cloudbet is also a casino with Blackjack, Baccarat, and Roulette. Join me at the Blackjack table at
Cloudbet.
Number Two Pick
Easy to use
Nitrogen Sports. Started out as just sports betting, but now they have Casino games. You don't even need to have an email to setup an account. You should either save the url to get back in your setting or create a username and password so you can get back into your account.
Number Three Pick
Great Casino where you can play poker or slots. Also a great way to bet on sports. Trusted name with payouts.
