NBT seems to be going for >$1.01 pretty consistently on NBT/CNY at Bter with respect to the yahoo feed. We could probably take advantage of this to hold a good bit of CNY on exchange.
So someone could put up a bunch of PPC, for instance, and be given NBT to go buy CNY with and hold it on exchange. At any point in the 3 months or whatever Nu can ask that person to buy NBT with CNY and burn it, or promote to Tier 1, or whatever the deal that’s been worked out is (flexibility is good here). At the end of 3 months, the person has the opportunity to request the PPC back via motion. If it passes, the person buys NBT or BTC with the CNY and gives it to T4, who will give back the PPC. Alternatively, the person can just continue the contract without much difficulty.
The issue:
What happens if the CNY cannot be liquidated on-exchange at the end of the contract? For example, what if there were no CNY markets and the peg is already breaking upward on the NBT/CNY pair? If we require the custodian to return the same number of NBT as they were given, suddenly they are taking on a much bigger risk. That’s fine, but it will need to entail a lucrative reward scheme.
