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.
Yes logically all the wagers are fundamentally loss. But when the actual balance is more than the amount invested, it is still a profit, which is the net profit.
