I understand the question.
But for a person to bet 9 out of 10 that he won is much easier than that he won 1000 and bet 500.
I defend the part of the person selling POB if necessary. I even need throughout the month to pay bills that are complicated. And I know that all over the world there are many people who are in difficult conditions and find a way to survive here. But, even so, at least the person will increase what he can in his stake. And not just selling everything.
If I notice that she has a constant stake in the amount she earns, then that's fine.
