gox makes money on the value of BTC, low fee's if the price is low ect, this is in mtgox interest to try and stop this selling. also any deals and partnership that they have lined up in future will be affected by bitcoin looking embarrassingly like penny stocks at this stage. nothing shakes confidence more that this. I don't believe I can trust gox at this point, also they are making it seem that lag is causing selling, but it's there dodgy system that can't handle selling that creates the lag, so they give out bad information about ddos'ers and there motives implying that you should not panic sell. they make it seem bitcoin selling wouldn't happen on its own.
