BookiePro is in beta right now, but they are totally decentralized and will allow for betting with BTC.
They are running a competition right now, giving away 5 BTC. Sign ups are almost closed though.
https://bitcointalk.org/index.php?topic=4434686.0I think you should not gamble online because most of them are scams and they will not pay you anything. You will just waste your time. I have seen many sites like this. If you are fond of gambling then to a casino and gamble there with your local currency. You will see everything in front of you. I just gamble for fun and not for money that why I never gambled online.
