Yes DB is probably the best bookmaker that accept btc just for immediately transactions (only 1 confirmation to get a win).
You can also try sportsbet.io because they have good odds, and a lot of market like first goalscorer, or corners bets etc...

I think the really revolution on betting with btc will provided by exchange bet, where you can "buy/sell" a bet (like betbtc.com) but with more money placed on markets.
