My personal opinion (based on gut feeling) is that most of that selling
already happened during the bear trend from $1000 down to $200.
My feeling is also that Karpeles was involved.
So you think their selling off drove the bear stage, and that they now are mostly sold - and that is why we are seeing a plateu and starting rise in price again?
Markets don't move entirely because of a single player, even a huge player like Gox.
So I wouldn't ascribe a simple cause and effect relationship like you're asking, but
it could be a factor. Also keep in mind there is still significant selling pressure from miners.
I do expect the havling that happens in 2016 to create major increases in price, although
that may happen somewhat prior as speculators position themselves. So part of the bull
run now may be anticipatory in that regard, although I still expect another leg up after
the halving.
