Well, suppose a player wins $10,000 on the last day of them month, putting you at a negative balance. It gets wiped clean, and then on the 1st of the next month, he loses it all. According to the casinos i have asked about this scenario, they say that you will be paid your share in the second month regardless.
I stress the “THEY SAY” part.
In this example, I cant see a casino being ok with this for very long.
