Nope, but I read it again and indeed that was what me got thinking about it. I mention @neo in the OP now as well as it’s quite close to each other (sorry, should’ve done before 
). The difference is in the client_managers and how they handle the “credit” part. It’s also close to David’s “burn to PUT” idea where you can buy low (burn a coin when the price is low) and use later on, if I understand correct:
This idea might violate the 4.3 billion Safecoin limit when it’s done with “cash”. For data not really a problem I think. Could be quite smart actually.
