I am playing from a long time and trying to make good profit for me, i am using simple strategy to play on gambling site never goes out of my limit because i had a bitter from my past experience by using martingale because nothing is guaranteed into the gambling world.
Actually that method can work but not in all type of games, if you are playing dice using martingale method then I am sure you will lose more if you do more. In sports betting that is applicable and I have tried that in my own, good result actually for me.
