>>>Bitcoins are point to point. They don't go through banks. There is no reason to have them accumulated by someone because you wouldn't be buying something that way. The only real possibility would be for someone to offer "cash" for bitcoins and then everyone would have to sell theirs. But as coins dropped out of circulation, the ones which remained would deflate (opposite of inflation) making them worth more in terms of real buying power.

13 bucks to 100 bucks in two months. Yeah sure LOOKS like a bubble. It still seems a bit odd though because from what I understand only about 1/4 of the bitcoins are even in circulation.

To me it seems more like manipulation than a bubble.
