Is is possible to change the Bitcoin price artificially?

[niotib]

Bitcoin is one of the top trading methods today. Suppose, if somebody could change its price artificially, Millionaire or Billionaire will be there.... Think along this.... somebody super genius created something with a secret "key"..... and he controls everything through that key....

I'm not expecting technical reviews, speak according to your common senses...  

What do you think?

It's completely and utterly impossible because no single entity can dictate the price of Bitcoin. Even exchanges trade at different prices. The price is a direct result of market movement, and no "key" will be able to change that because it isn't embedded anywhere. Even if someone had all Bitcoins in the world, they wouldn't be able to fully dictate the price because they're only worth as much as other people want to pay for them.

It's hard to speak on even hypothetical terms because if the premise were true, then the world dumping would have no bearing on the price whatsoever. I guess it depends on how long he can keep it a secret? If the world knows, then they'll dump and no one will want to buy anymore, no matter how low or high he sets the price.
