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.euIt is not ethical to advertise through other threads. I cant stand companies doing that! BTW one company, which used the same betting solution without depositing, went down! It was outright scam - Bitcoinsports.eu. I wouldn't call it "That's as safe as it gets", because it is not.
https://bitcointalk.org/index.php?topic=439668.0With the recent closure of MtGox, and so many Bitcoin sportbooks that ran away with the deposited Bitcoins, it is clear that your Bitcoins are not safe, even when stored on an exchange, and I believe it is important to educate the people here that they should keep their Bitcoins in their wallet as much as possible.
As a company that provides betting services, we came out with a unique solution to this issue. We are currently offering the safest way to bet on sports with Bitcoins.
The other site that you mentioned did take deposits - from investors, and the investors were the ones who suffered most of the losses, or those who kept betting despite not receiving their winnings.
We on the other hand don't take deposits or investments. We also provide a guarantee that you will receive your winnings within an hour (or else you get a free 0.02 BTC bet !), so you have control of your Bitcoins as much as possible.
