Remember that if someone is going to dump 1000 coins on Gox now, we would approximately go down by 40 USD. The guy doing that would have pocketed around USD 880.000, but the Bitcoin marketcap would decrease by USD 480 Mio.
Thats why Bitcoin market cap is not usefull indication of anything,
what matters are the buy orders placedThis is a false sense of security!
Most of the bids have no intention of buying unless the price drops first to hit said orders. Many of those will be pulled and replaced at a better price or not replaced at all. Much of the bid side of the order book is just fluff... Padding and propping the price.
On the other side, I read a lot of posts talking about the cumulative ask depth and that there are believed to be "only 12K Bitcoins for sale" in existence.This is another wrong assumption. At these prices, where no one can truly know where the top is, most sellers don't place asks. They wait for their price to get hit before just dumping on the market. After all, they wouldn't want to create unnecessary resistance 'To Da MOOOON!', would they?
