Except there doesn't appear to be a whole lot of dumping going on. I suspect the majority of Bitcoin investors are more interested in seeing how far Bitcoin can go rather than dumping all their coins the moment they've made a reasonable profit.
Yes, that is the interesting bit. A lot of people are not in Bitcoin for the money primary. They are hoarders or altruists.
Once some person tries to cash a $50,000 BTC account it will go down. The market depth is simply not there it seems. The money supply is not regulated vs. the trade volume, right?
