Casinobitco.in - 4 Great odds, no live betting but I only bet in advance so it doesn't affect me.

Betcoinsports - 3.5 Odds not as good as Casinobitco.in but more selection of sports and live betting. Great support.

Webetcoins - 2.5 Slow grading of tickets but they are supposedly switching to an automated system. Also, only straight wagers available right now but they said parlays should be available next week. I will update my score as they make improvements.
