On Bter, a 15BTC dump could bring the price of BTC to $1. The same 15 BTC purchase can bring the price to $580.00.
Its worse on Cryptsy. 5BTC could drop the price to $1.
The problem with the BTC market right now is lack of activity. The thinner the market, the easier it is to manipulate the price. Usually the manipulation is DOWN. For example.......... the silver market!
Yup there isn't much liquidity in the BTC markets. I think bottomline BTC is pretty much being moved back and forth between people already having it.
I took the time to buy in with more FIAT but I am currently sitting fiat, I will buy BTC and XCR with it & since I have my own company I take salary.
I want XCR/USD because Bitcoin can't go on forever with the ASIC race.
