Treat gambling as a small business. Once you get your capital money back in your pocket plus 200% profit, you'll maybe use 30% of it and bet it again... if you lose, you'll try another maybe 10-20% again from your profit... and so on. it won't stop..
You can use that strategy to use 30% of your capital money to continue gamble, but you must know that when you lose, you will use the other portion of the money, and you can use the profit that you got before. If you cannot control and stop your game, you will end by losing all of the money plus the profit, so you will be sad and regret why you did that. If we talk about how much money we need to stop gambling, actually, we don't need to win much money, or if we lose, we can stop right away so we can save the rest money for another day.
a typical gambler cant stop as long as he still have some balance left on his bankroll because they intend to deposit that amount in the hopes of hitting thier target payout but idk if they hit earlier they can stop or will continue with higher bets but the often one that i see is that they play more with higher bets and idk what happen next to them because they dont update us if they loose or won but they just dissapeard completely in the chatbox .
