Situation which mostly affects or a factor that affecting those gamblers who can't handle the difficult situation when they suffered from loses.
Most of us find it difficult to earn money because we earn it with our effort and work, it is normal that the things we do when we risk money may cause us to feel some fear, dread, even some people feel panic of losing money, but if there is not enough money to risk and be willing to lose in a casino, then there is no need to do it, you just have to do it until you are completely sure that if for example 5 or 10 usd can be lost without affecting our economy, otherwise it is not good to take risks.
I see, you talk in the angle of affordability, and yes, you are correct, once a gambler can afford it, it could allay fear, but I tell you still, that's to a certain degree. Human nature varies and the importance we place on money varies. Some people can afford a certain amount but they are still not letting go because they are, for instance, stingy by nature. Such people will not take it gently when the least of their money is lost.
However, stinginess is just one, there are many examples that make people fear by attaching themselves to the money, which will cause the opposite of a brave gambler's mind.
