Well said bro, I keep wondering why people believe there is a winning strategy in gambling. This has never crossed my mind because I understand that beating the odd is absolutely impossible. It has been made to be in favor of the site. Like you said and I completely agree, take your little profit after each win and go home. Don’t ever think of double betting or recovering loses, this way you are opening doors for more loses.
I have and will always be against martingale strategy. It has never favored anyone I know and whoever came up with this strategy obviously did it to deceive gamblers because it really sucks and has led many gamblers into debts. I know of a gambler that borrowed money from his family to gamble believing that martingale system will enable him win, he lost it all completely and went into depression at the end.
Actually it is not entirely the fault of the martingale system, it is more a mistake in each of them. Many of the gamblers chase martiangle with high emotional states, especially when the first martiangle they lose, it will spur chaos and even add to the defeat.
The martingle system still works well in my opinion, only if the gambler can wisely use this system. It's useless if many systems are used but can't manage bets after losses.
Like me, I combined the parlay and martingle system and so far it's good for me. Of course I am not risking what I cannot afford to lose and I am managing all profits and losses well.
