Hey all, nupond operator here (i run the liquidity pool on bter).  NBT are held fixed to the dollar through a multi-tier system to ensure we have deep decentralized pockets.  The money on exchange is just tier 1 and 2 and while it is important for sensing pressures on the peg the orders on the order books are not the be all and end all of our liquidity.  The end all is Tier 6 which constitutes us either buying or selling our own shares to cement the growth or shrinking of our nbt supply into the value of our own company.

Tier 4 buy side constitutes (currently) a multisig address ( 5 of 8 ) holding bitcoins that we can use to refill our buy side liquidity when required.  We have passed a motion that states our intention to hold 15% of the circulating nbt supply as a btc multisig reserve in Tier 4.  We are developing and growing every day such that we have deeper and more fluid reserves on both buy and sell side.
