Does anyone know a good betting site besides Pinnacle Sports, that doesn't limit winning players? Not that I am winning, I dind't try it before, but if I could win, I don't want to be limited.
Your best option is likely a betting exchange (like betfair) rather than a traditional sportsbook.
With a betting exchange you're betting against other punters and the site just takes a commission from your winning bets (similar to a poker room and rake). So they generally don't have any reason to limit winning players.
