I am sorry, but I am very much against this. 10% a month for providing USD liquidity is not worth it. Think about this:
There is a bitcoin trader looking to cash out some bitcoins to his bank in Denmark. CCEDK has low fees for withdrawals in Denmark, just speculating. A Denmark bitcoin trader sees an opportunity to cash out $5000 with NuBits. He trades his bitcoin to NuBits and then to USD. He makes the withdrawal. Now there is no buy side liquidity on NBT/USD for the next 30 days.
If this likely scenario were to play out, the network paid $500 for this trader’s single withdrawal. He would have a very hard time cashing out $5000 worth of bitcoins on CCEDK otherwise.
