I know that as gamblers, everyone can relate to this question, as we have surely experienced it in real situations.
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 used specific amounts to make it easier to discuss this situation. I understand that we all gamble with different amounts based on our income, but consider this as an example. You can mention any amount you want based on your personal experience; it doesn't matter.
it is difficult to determine which event is easier to stop, but I myself have a thought that winning in gambling is something that is rarely obtained, maybe even difficult to happen and get, so I prefer to stop when I have won because remembering that victory is indeed difficult to get so it must be used as well as possible, immediately cash it in and not bet again. Likewise with when experiencing defeat, when you have experienced defeat then stopping is a good choice because winning in gambling is not certain even if we continue gambling again does that guarantee? of course not right?
in this case maybe awareness and self-control are things that will determine everything, with awareness of course the profits that have been obtained will definitely not be wasted, I myself am like that. and vice versa, if there is no awareness, maybe what will happen is a greater desire to win which will actually be a disaster. even though there is luck but that doesn't guarantee it.
