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.
yes you are right, as it is the specialty of bitcoin. and different when compared to the obvious altcoin there is a developer behind it.
bitcoin becomes the most promising crypto in investment or trade. that's why bitcoin evolves as the times progress.
