It's the same with the normal slots depending on your desire if you're wanting to bet more or not. As you've said, after 30 minutes, you easily get bored and you might tried to find other games that will remove your boredom. It depends on how active you are but most gamblers that do get bored easily, they won't stop. They won't even cash out so it's a question that we all can answer ourselves because it'll depend on how much it is in our balance but sometimes even if it's a lot already ,we won't withdraw it.
Yeah it's our own decision making and like what you said even how decent the amount we already have we still trying to push for it and aim to win more, it's about how good you are in controlling yourself, though most of the time it's greed and too much excitement that lead a gambler to continue instead of cashing out and enjoy whatever the earnings that he already gain from the game that he's playing.
Basically when we talk about money then it will be very difficult for someone to be able to limit themselves, it is unlikely for them to be able to ignore greed in themselves because what is in their mind is that they have to get a lot of money to meet their needs and all their desires and that is why when a gambler has got 10x the capital they brought but still they do not feel enough and continue to play to get more. Attention to the consequences of the activity such as risk is really very easy for a gambler to ignore when they are caught up in the extraordinary joy especially when dopamine levels in the brain have increased, and this is the reason why controlling oneself becomes something that is very difficult to do, in the end often only regret is what they get, so it can be said that if for example a gambler wants to be free from the problem of greed then they must really not make winning a priority.
