Maybe I'm not seeing it, but I just don't think this is that cosmic of an event.  Bitcoin price is already recovering.  It's not like we learned something that we didn't already know (that keeping large sums on bitcoin exchanges can be lucrative for traders but is also playing with fire).  The 1% of total bitcoin stolen probably will either be returned to circulation by the hacker or by a combo of the exchange and miners.  And even if they are gone forever that just makes the remaining coin more valuable.
