Everyone with its own playing strategy and I wouldn’t have to condemn your strategy because at some point, it might be working for you and as such, I don’t have to start disputing that.
But I have some few questions for you:,
What if you loss your capital for maybe 5 consecutive times in your row, will you still be able to continue that your strategy and will you still be willing to want to double your money,
In a situation where it seems the casino is favoriting you, and you get to make maybe a little more above your expectations without any much stress, will you be able to stop for the day or still want to try your luck?
Personally the moment I make some winnings and I feel ok with it, I always leave and stop playing at the moment.
Maybe OP is looking for risk management methods suitable for his game style. Gambling is not a guaranteed action, everything happens in probability so the money the gambler risks to put on the table shouldn't be more than the amount he can't afford to lose. Some gamblers like risky gambling behavior and keep adding stacks until they beat the casino but this happens for a short period. In the long term, the casino always wins and no strategy is reliable to make a guaranteed profit in the long term due to the math behind the casino games.
