The other reason that this might happen can be seen by looking at the current state of the paper gold futures market. This market is being used to artificially suppress the price of gold. At some point, these paper markets are going to fail and it will be the holders of the physical commodity which will benefit. Is the Bitcoin futures market being used in a similar fashion? I'm not sure, but it could be and the same thing may play out for Bitcoin. Only those actually holding the keys will be able to transact on the network.
