It seems like that the recent fall is due to a disinvestment from MT. GOX. It that's true, the recent dip is not much of an issue
It depends. If they keep dumping, it keeps affecting the market, but if they took a temporary break, the demand should push the market back up again. If the price goes down anyway, then there is a lack of short term demand.
The thing is that we don't know if mtgox coins have been dumped this week or last week, unless they announce it afterwards themselves. We operate solely at their mercy in that regard.
I wonder if people here have been trying to find the addresses connected to the mtgox holdings. I tried to do some basic level research myself, but haven't found anything pointing at their coin stash(es).
