There are always some master minds behind such mainstream news. This might be called as a business running strategy as we all know listening to a news like "Facebook is on the verge on banning cryptocurrency" will make peoples think that the price for bitcoins reach the bottom and they sell as early as possible.

Once, they sell their coins, the big whales start buying at the dip as already they know the truth behind the news so they are the one's here who will be in profits. Depending on any such news source is really non-appreciable. Always invest without own research and sometimes thinking differently can make us have more profits rather than going along with the flow.
