Yes, it is very difficult to win with such a risky strategy, it may have worked for OP, but I think something like this works once, and then I don't think it works, for me these things are also very much due to luck, at the moment,
The problem with why there are people who think that martingale is good is because of that once-in-a-lifetime experience making a profit out of that betting style. Since they have won, the method they use will be registered in their mind and they will consider it an effective strategy.
That's why I told OP or anyone using that style to show their betting history.
Maybe their winning experience thru martingale wasn't able to make a repeat and now realized that's it not a way to win on dice.
Just let them be on what they do believe or what they do seem its right because once the reality would slapped into their face then this is where realization do kicks in.
There's no way you could really beat up the house or beat up a gambling game.You would eventually lose in the end if you arent that smart enough on getting yourself out when
you are in profits then you would really be still ending up on such situation.You would really be making yourself that desperate if you do believe that theres a strategy
or method which you could really take advantage and able to milk out a gambling platform or casino.
