No matter the strategy we chose to use or test for our gambling there can't be a guarantee on any to give a hundred percent streaks of winnings, gambling is a game of chance we can only establish a strategy to reduce impending losses and not that we're beating the house because the house has the hedge while we the gamblers has just luck on our side particularly in a game like coin tossing. When on a losing streaks martingale isn't a strategy to consider for the anticipation for recovery that surrounds the whole idea of the theory is mostly misleading.
It true, there is no strategy that can truly guarantee victory and can generate certain amount of money for its users.
But on the other hand, there are positive things that can be taken from what the OP has done, he is experimenting or testing the strategy he has and of course to be able to see whether the results are truly reliable or not.
There is experience and understanding that can be gained and this is the positive side of testing strategy or game.
We will have more experience and of course this is lesson to be able to create other strategies to increase our chances of winning.
Even though it is not guarantee, at least using strategy can give us confidence in our abilities and we must be able to accept all the results that occur.
But you still have to be in calm condition and also use the smallest amount of money in each bet, the aim is so that the losses that occur are not too big.
When we have carried out series of experiments with the strategies we have, this will indirectly develop thinking so we can learn again to create new strategies.
I know maybe this will be in vain and include throwing away money but it is much better than those who always follow other people ways and have big ambitions to win and make money.
The more experience and more learning it will make us smarter and more responsible gamblers.
