I think nobody can control or own the bitcoin system like they can not control and possess the technology by email and the internet. I think Bitcoin is no different than a mobile application or program that offers a personal Bitcoin wallet and allows users to send and receive Bitcoin.
I thinknno one controll the bitcoins system but us the users that thing is just being invested and then leave it by its own so i think it is a pure conputer that cannot be hacked because of maximum security. Maybe the only thing that can access it is the one who male it but no one knows who really the man behind it because it can be me or you no one knows. Or maybe there are really a person behind it controlling the price but we do not know there are a lot of possibilities in my mind.
