Scam or not, if people are willing to pay an amount for Bitcoin they aren't worthless regardless of whether the purchase was based of the false pretense of a listed price.
and some people here don't want to "accept the Fact" that they have been tricked...
The only way what he claims can trick people is if they don't bother looking at any other exchange prices (such as at MtGox or bitcoincharts.com), and only buy all his coins from him. If they do (as I bet most people buying bitcoin do), then they would have just thought his price was too expensive, and bought elsewhere. Or worse, the sellers would have thought his buying price was better, and sold him all their bitcoins instead of to exchanges, in effect making HIM pay more money for their coins. It's pretty stupid over all. Especially considering that MtGox has typically been the price setter, and that other exchanges (much more prominent than his I'm sure) have also had typically higher prices, yet had no effect on the overall bitcoin price.
