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.
That's true there is no assurance whatever strategy we are going to use in gambling because there are just 3 results if we are going to gamble. It's either we are going to win, lose or remain without loses and winning. I think the most effective strategy when you are going to gamble just know your limits, just like what you have said.
