I think the OP is a little misleading. As the mtgox crash showed us, there are hundreds of thousands of dollars sitting on the sidelines. If my memory serves me correctly, $1.3M worth of orders were filled by the sell off down to 0.01. Sure, some of that money may have moved, but I doubt that anyone was able to while mtgox was down. It is probably still there.
Memory not acceptable as data. What I have shown is the entire book according to the above site. If you have a better source please share it.
If 0.3% of the market was really setting prices, it would be entirely too easy to move funds into an exchange and shake these "market makers" out. If bitcoins were significantly overpriced, there would be an influx of bitcoins to exchanges and prices would drop.
There is faith in a higher price.
