Too many noobs are playing with people's money. It is good to have more than 2 exchanges but not this way.
However I don't really think this is going affect the market much or at least it shouldn't
. We're probably talking at most 3-5000 BTC gained from the hack which might be able to put a 20cent dent in the market but apart from that I don't really see much happening.
What worries me is that this hack might actually have happened a while ago and been covered up for 1-2weeks during the a lot of extra peeps might have been taken to the cleaners.
