Could you help me with these two questions?
In a flash crash, margins would be called and bitUSD holders would end up with btsx worth of their bitusd. They would only be hurt when btsx falls furter after the margin was called. Is that correct? Because I often hear BitUSd could be uncovered in a flash crash. That (to my understanding) would only be possible if the flash crash happens so fast that the system can not automatically call the margin, that would be 1 block / 10 seconds?
Also, are there BitUSDs with different margin call limits floating around in the market because those bitUSD where shorted into existence at different BTSX prices?
