Suppose our bankroll is $100 and it has already grown to $500, would you quit or continue? Conversely, if with our bankroll, we are down to $10, would you still continue or save the remaining $10?
i’d take the $500 and go thank you
i am not one to keep myself bleeding down to the last cent if i notice my money decreasing and not getting any profit then i would take that as a sign to stop and take my money to put into better things that could potentially give me profit instead
That's how it should be. If you're in profit, be contented so just quit. However, not all gamblers are able to do this because of their greed to gain more. The reason why it's much easier to stop once your bankroll is slowly decreasing. Because that's the time you'll feel a regret for losing your money in gambling instead of spending it into other things. Thus, it is likely you will save what's left before it's too late.
This is why it is easy to lose it all to the casino due to one not having the strong motive of quitting the game when losing or winning for those reasons which you mentioned above. Self control and discipline are something that one needs have so that in a situation whereby he is winning or losing, he can easily quit the game when his because he has set a time limit for his gambling activities.
Also gambling with an amount of money that you can afford to lose helps the gambler to quit the game when he has lost the money because he has exhausted his gambling budget for that day but if the gambler is winning, he might continue playing.
