No one off course gets any limits for winning. This would be crazy. Some win, some lose. That is the nature of the game.
Only you may get limit, if you main purpose is arbitrage betting (surebetting).
I've had some friends on skype who I recommend your book to when I first started using it, and one of them told me that they couldn't place 50 mBTC on a popular soccer market after placing 2, 500 mBTC bets. Also, my personal limits went from a high amount to 100 mBTC, and than kept dropping as I got closer to finishing my bonus (had to place very small (< 20 mBTC) bets when I was almost complete.)
Well Darkstar,
Now I know your accounts and those of your friends. You advertise a bet only surebet positions. (arbitrage)
You have a nice thread here, which you participate in and explain.

Again, primarily arbitrage betting (sure betting) is the only reason for getting a limit on your account.
