Bitbook is the only online sportsbook I've ever used. And I've been nothing but pleased with their service. My only complaint would be the speed at which 1st quarter/half wagers are graded. I had a 1st quarter bet on tonites Seahawks game and it was just now graded in the 4th quarter. Had I had those coins earlier, I would of re wagered them. I usually bet small amounts 0.005 to 0.01BTC. Is it the withdrawal limit of 0.01 that people are complaining about? I understand the principle of having access to your funds at any time. But being that upset over $8.40USD worth of BTC seems a bit much to me. But, I've been in urgent need of money before, so I know what that's like. I've never had any worries that my coin at bitbook was in trouble. When they were having odds issues earlier in the week, I was still able to withdraw my 0.032 immediately.
