That's exactly. Im agree with u. Its just gambling. Bet, win or lose its not E=mc².
But it is (martingale method) nlose + win = win + quit = win. The only method that work to book a winning is quitting if you are winning. Else you will lose em all. So the best strategy is having control of yourself and know when to quit. That would sum it.
well said mate the computation will give you a win if you are not so greedy to keep aiming for much larger wins, as long as you already have some winnings its better to keep that way the more you can quit while you still at win the more advantage you have against the house nothing is changeable if you can follow these simple step quit while you still at win.
