What Loaded meant is that he has loads of customers who bought at $10-$100 and are eager to take part in Bitcoin's profits, but do not care about suffering its downtrends. He need to unload perhaps 10,000s of coins and is doing a good job manipulating the market to look like a good opportunity for the small traders to buy in. To sell the coins at this thin market a crash is required - there is just not enough volume in the updays.
In general, there is very little buying interest above $400. The smart money knows when there is more air in the bubble and has no problem waiting for not only realistic valuation but preferably despair.
