Very few people can win in the long run. For each that manages to do it, 1000 others ruin themselves by being too greedy.
We are probably living in different worlds. According to this thread(and most people) success in gambling is 99% luck. But to me, its something like 95% hard work, and 5% being the right type of a person. Luck does not matter because it evens out in the end.
And "1000 others ruins themselfs by being too greedy" is not entirely correct other. They dont lose because they are "greedy", they lose because there are no reasons for them to be winning in the first place.
And even big winner may lose everything by bad luck, and then what?
Not really possible to "lose everything" with a proper BRM
