stupid ? but what is

[Penguinfan]

This is something I just can't seem to understand as well and I have read a few definitions and several threads on the subject, but just don't quite get it.

Say I buy $50 of a BAP and it busts to zero, the guy doesn't cash at all in any tourney.

He now owes me $50 worth of cake (I think).

In a future BAP he states you may collect on past cake and I decide I am going to do that, what happens?

Do I now have $50 worth of that BAP (what if he doesn't cash again, does this go on forever?)

Or is it a case that IF HE PROFITS he pays back my $50 and thats it?

Man, I hate not being smart.
