I thought we were escaping the insanity?
What this does for bitcoin is introduce a way for those wishing to hedge or short bitcoin a method to do so.
This will help the Bitcoin exchange rate to be more stable.
With short sellers, the higher the exchange rate, the more speculators who will bet agaist bitcoin.. If (or more likely when) there is a sharp selloff, those who are short (but not those who are crazy calling for $0) will become buyers, and a lowered chance of insolvency is the result.
