What is your point? That price kept dropping for several months after all this happened? Or something else?
Yes, that's my point. The Gox fiasco was a catalyst that led to the continued decline.
I see. You are looking at the downward trend until ~Dec 2011. But didn't it start with the crash before the hack? What makes you attribute the downward trend to MtGox hack, as opposed to something else? Or to many other things? Or to typical random fluctuations in markets with lots of players and little rules? Most importantly, there were other major hacks and thefts that did not trigger similar months-long downtrends. Doesn't this prove your hypothesis false?
