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.
I agree. Most bad news that affects more the Bitcoin's price is when it came from the government or to some big international companies. So these only means that it doesn't matter what's the content of that news. The thing is, "Where it came from that matters most."
So the government and the big institutions can really manipulate the price by their words.
