You have given us very good strategy but in the real sense it doesn't work , if it where working every one will have been making cool cash from gambling
Strategy does work very well in skill based gambling, the challenge is that most of you do not have strategy and felt that what you have is a strategy when it is not. Strategy should be comprehensive enough to compensate for down times, which are times of losses but unfortunately, most gamblers do not want to see losses and when it happens, they abandon whatever method or strategy they are using because loses were never part of their gambling strategy. Strategy truly work in gambling , it's just for the gambler gambler setup one and follow it religiously.
No one for sure wanted to lose their money though like what you have said, there are gambler who set thier strategy then failed to follow when situation turned against them, the chance of making money is a tough one in terms of gambling as even how good your strategy you don't the control when luck will permits you to win decently.
And even you already have that chance sometimes you forget to follow your strategy and eventually you'll lose back the money, instead of taking it and quit your way you got greedy and push for more.
