Each and every site of sports betting will have their own rates on the event , Their are some sites where you have to create the account and deposit and then you have to play , they run some promo on deposit. Like Anonibet, Nitrogen, jetwin , their is one site called Directbet.eu which i use to bet my sports for live inplay and pre match also as here i dont have to open account and keep funds to play, here when ever the even is their you just pick the bet and the odd and then they will generate a deposit address just deposit the fund which you want to bet, on winning that bet profit will be withdrawn automatically.
