Op I don't get this method. Cause we should Focus on games, and will only stake if you have better winning chance. And should happy if you win whatever the amount is. But if you focus on double your amount then you'll have to stake more or stake high. Thus you have more possibility to lose. I think we should only stake on our favorite games what we understand and have kore possiblity to win (according to our analysis) and then good to go. If win they okey, if lost then wait until a good game for Stake. I follow this strategy. We shouldn't stake anywhere randomly cause i found, most of the time we lost in that situation. Even double money is risky step. Think again, is it really easy to double your money Within a day? That's huge risky. Even you can lost all what you won from previous bets
Gambling will not be as easy as imagined, even if you play or bet only on your own favorite type of gambling, but in reality there is no guarantee that you will be able to win every time you bet on the type of gambling that you like. Also, the reason OP bet and doubled money and then quite, it's not always about doubling your money. So what this means is, when you bet and then you win regardless of the result or profit, it would be better for you to quite.
The reason for creating a theory like this is because when a gambler wins, it is very likely that the pleasure they get from winning will make the bettor become complacent and continue betting until they end up losing. Therefore, the theory that OP made is basically not wrong, because such a theory would be good to apply, because when we win at gambling it will also make it difficult for us to stop, but OP has reminded us.
A human instinct that they can keep continuing the winning streaks but in reality it's a way of the house to keep engaging the gambler and at the end of the day, if the person is not wise enough, he will end it up losing. There's always limitation as you mentioned even how good your knowledge about the game, there's no guarantee that you can keep winning, the only way for you to take the advantage is when you win you cash it out and rest for a while, enjoy your winning and avoid yourself to play back.
