If you want to bet with bitcoin than i suggest you to try directbet.eu, sportsbet.io also used to be good but they have got few open scam accusations recently. So i don't like to suggest them to anyone.

Another good sportsbook is nitrogensports.eu and i have made few bets there before.

I am using this site for few years now without any problem, i use them to bet with perfectmoney not with bitcoin. I have also won few $ on bayern vs madrid match there last night.
