In my opinion, it is still the quality of news that really affects the Bitcoin price, fake news spread by fudders will not affect the pricing, the question is what is the news? where it came from? Is it real? Most news affecting Bitcoin price are those news came from the government, those news that really made against the Bitcoin like banning from a certain country, declaring it as illegal and the likes of them.
Oh, I think you are wrong here, infact FUDers can do a lot of damage in people's brains and affect the price. Mass media are doing ther job correctly and make people scared of Bitcoin.
