Didn't bothered to visit the stuffs at the site because it's not a good thing to bet on WWE or all I can say is, is that really possible? Matches are fixed (because of entertainment) and in the past (The Rock, Stone Cold etc. era), Im a regular visitor of their site and the match results of an event is written on the website in advanced so how come betting is possible here if they are listing winners there before the telecast? That's how others knows the result in advanced, I just don't know if that is still present in their site.
AFAIK, there's no betting site which offers betting on wwe matches. better bet on UFC matches, it's real and not like wwe(scripted).
Yeah better bet on UFC or URRC matches or some general boxing events both local and international rather than on WWE.
