I said limit the profit. I never said limit the payout. Example, you invest 0.1 btc and play.. When you are up with 2 percent profit or 5 percent profit, just exit the game. But mostly people never do that, they keep on playing and finally end up losing everything.
You can substitute "payout" with "profit"which I have doneand my argument still stands: All wagers you make are fundamentally unprofitable, regardless of when you stop playing.
