When it comes to investment the human factor will always come to play which involves FEAR, when ever you see people panicking over their investment their must have been a negative news that triggered the Fear making people to either their funds or sell off shares. This is the same case with cryptocurrency, when their is a particular FUD, you see the market going down immediately.
