This crash proves to me that we need a base supply of both BitUSD and BitCNY.
If whales like @bitcrab need to exit their positions we need more BitUSD and BitCNY in the system.
We need a massive dedicated account used exclusively for creating BitUSD and BitCNY.
This account should have all of its BTS as collateral at all times and hold no other assets.
It should be funded by a rolling worker proposal.
The BitUSD and BitCNY created would be used to purchase any BTS below the settlement price.
The BTS purchased would just get added to the collateral.
The account would never pay back its borrowed BitUSD and BitCNY because that would destroy the supply.
I really think this is needed for BitShares to be successful.
