not sure how that'd work
Just use points, with 1 point = 1 cent.
if that's even allowed
It is and either way you can't really be stopped from independently transferring money for winning a WZ competition. You never do a friendly video game tournament with a small cash prize, or play poker with friends?
If you're worried about the law, well, technically they would have to report it as income but that's not your problem.
