If I bought a 20m vanity and wants to sell it for 500m, is that manipulation? No. That's my right. I can always sell for the price I deemed fit.
It will only be manipulation if there's an intent to deceive and has involved a series of fake offers or transactions - making the other party believe that it was actually selling for a particular price.
But then again, if you buy a vanity for 500m that was selling for just 20m a week ago - that's called stupid (but still within your rights).
