Arc, you are confusing a betting system with money management. You wrote: "You can't change your future expectation with a betting system."
Money management is not a betting system.... unless of course you want to define it as such.
I think of money management as a tool to limit your losses and to let your profits run, just like investment pros do in the world of stocks, and as businessmen do when they start businesses -- letting the strong ones continue and shutting the losers.
Your other comments just show you are at a loss for words and for reasoning. You are standing your ground, Arc, and your feet are firmly planted in quicksand.
