Bitcoin is open-source; its design is public, nobody owns or controls Bitcoin and everyone can take part.
I always say: Bitcoin can be controlled by Media.
shouting (making your text big and red) does not make it more true!
the fact is, any asset in the whole world is affected by "news" and news comes from the "media". the effects are different based on the news and the asset. but the effect is inevitable.
with bitcoin, there are far more idiots investors than any other asset. that is why the swings are also bigger. but also there are a lot of opportunists who will gladly take their coins out of their hands under market price.
you can not really call this "control".
