Bitcoin is a symptom of the internet right? so whoever controls the internet controls bitcoins..
Can the government shut down the internet? Yes they can!
So who controls bitcoin?

I was just watching a conspiracy video on youtube.
It was talking about how the government can shut down the internet, the actual video had nothing to do with bitcoins, but surprisingly the main reason of the shut down was because of an impending financial collapse caused by Israel attacking Iran, since they disagree withe the nuke deal, something looking very likely to happen..
here is the video
