Not greedy enough to suffer the long losing streak, those who got good balance maintaining their time of playing,
Just like what you have said, there's no correct answer always in between. even if there's someone who claimed that the strategy works for them, it doesn't convinced those who suffered big losses, and coming from majorities this system always bring heavy losses to the gamblers who lean on using this system.
majority of them does know that martingale strategy do sucks and does really generate more losses than wins and they cant really just accept the truth and trying out to be good looking into other gamblers eyes that it does work for them but the truth is that it doesnt really work.It is really varying on how you would really be handling out yourself on using strategies because theres no such thing on this world that gives out guarantee and that should be always be put up on someones mind so that they wont really be that expecting much.
I have seen crazy streaks in roulette of one color showing up more than 10 times in a row. It is insane, but from a statistical point of view absolutely possible. The OP explained very well how the mathematics work against you if you look at it from the opposite perspective. How many games do you have to apply the method such that your chance to lose is almost 100%, and there you have it. I admit when I was young and started playing a bit I also tried that out and I learned my lesson with cents, which was good for me. I started with a cent, and then two, and then four, and I was shocked how quickly that escalated to my disadvantage. I always thought the casinos were rigged and then did my research accordingly, and the result was exactly what OP explained. For those who don't want to trust in their belief, just trust in maths!
