Another idea for you. Go ahead and send pshabi the $10 now. IF you lose, you're even. If you win, he'll send you back your $10 plus the $10 he owes you, for a total of $20.
This might sound weird, but we all know pshabi and I'm telling you that you can trust him. We don't know you as well yet
If for whatever reason,m pshabi screws you over, I wil personally send you the money he owes you... I'll vouch for him.
