Look into groupthink. Bitcoin is a social experiment so ny default the thongs thay drove social discourse will drive price.

Because news can instill fear or confidence. With something like btc, if the news is laced with fear it will likely prevent newcomers coming into the market and mass adoption.

I agree with @accra and @h00pla85 - With Bitcoin we also have to remember the major influence that social media including platforms like Steemit can have on the way people think and this only heightens the fear or confidence mentioned above. However, as I said in my OP it's very difficult to really measure what impact an individual news story has on the price of bitcoin because it's impossible for us to know how individuals will interpret the news and then act on it.
