I have seen a lot of betting sites/ gambling site who use bitcoin. Betting site and online gambling are now become more popular simply because of bitcoin. Most of the gambler have bitcoin and they use it to play. In addition to that, all betting and gambling site have variety of gambling games where can entertain all gambler. Right now I keep on playing in betting or in gambling site but before I play I will make sure that I have enough luck in playing gambling and I prefer to play card games like poker and black jack.
