"Nobody owns the Bitcoin network much like no one owns the technology behind email. Bitcoin is controlled by all Bitcoin users around the world. While developers are improving the software, they can't force a change in the Bitcoin protocol because all users are free to choose what software and version they use. In order to stay compatible with each other, all users need to use software complying with the same rules. Bitcoin can only work correctly with a complete consensus among all users. Therefore, all users and developers have a strong incentive to protect this consensus."
Like if a person owns a lots of bitcoins then he is alone can control the market vs USD. If that's what it means then how can it be secure? It is nothing more than a software and we can never know its market movements fundamentally. Anytime Bitcoin vs USD market can be a scam right?
