This should serve as a reminder that your Bitcoins are not safe when you deposit them into a sportsbook, no matter how long they are in business or what their reputation is - and Bitbook was considered the most reputable Bitcoin sportsbook at the time !
For this reason we've created DirectBet. We came up with a unique solution where you can bet on sports events without depositing your Bitcoins and parking them on a 3rd party website. We do not hold your Bitcoins except during the lifetime of the bet and only the amount that you wish to bet. That's as safe as it gets.
http://www.directbet.euProbably the stupidest thing I have read in a while. Nitrogen only holds the coins for the lifetime of the bet too.. They have instant deposits and instant withdraws. Technically you actually hold the bitcoins longer than multiple sites because you require a boatload of confirmations. Secondly, The the juice/vig on your games that haven't started are OUTRAGEOUS. The live bets that are posted have huge amount of vig incorporated in them. Directbet is nowhere near the competition.
