Looks social medias can now affect it, many people who are can share the various things in some social media, whether it's debilitating or pushing, the core is not a particular companies only.. some people write, make video, or share many things related to crypto in social media to influence the reader, the viewer, and certain people.
It goes for the #2 and they are really being used by people who wants to push something. If they want to see a massive dump, they'll publish something which will lead people to panic sell and if they want to see a massive pump, they'll publish a lot of good news about adoption and other positive news that will bring others to invest more money to bitcoin.

This factor should be under #2.
