Better question why hasn't anybody with 1 million + bitcoins started a commodity fund on the NYSE, TSX or other exchange. That's how gold and other commodities are traded and price determined. Would remove lot's of market manipulation if traded like every other commodity though then you'd be trusting wall street T Boone Pickens hacks to not screw us all over, but at least there would be transparency and some sort of regulation to prevent a big trader on Gox doing whatever they wanted
I'd seriously doubt that there is any single person that has 1 million+ bitcoins, and if there were, it'd be Satoshi. And I certainly don't see Satoshi having anything to do with the normal financial systems.
As for why hasn't some billionare bought up gobs of bitcoin with the intent of pumping & dumping? First off, pumping & dumping is illegal. Second, billionares tend to prefer their own reputations to remain as publicly clean as possible. And finally, how do you know that some billionare hasn't been buying gobs of bitcoin?
