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.
bitcoin is controlled by all of us
agree with this, but still there is a dominant to be able to control the bitcoin of course that have a lot of savings and trade by looking for huge profits.
One advantage of bitcoin is that it is a decentralized system. It is not under the control of one central authority or government central banks. What influences bitcoin is the people using it. So bitcoin community will grow as more people support it. There is really no central control. What we do influences how bitcoin develops.
