There are definitely impacts of good news over the price of the bitcoin. But I dont think any bad news could have affected the prices that much. Many analysts have predicted in the beginning of this year that price of bitcoin will go below $5k but the current price is well above $7k.
Media has a power to manipulate and change the mindset of a person. It affect the investors of bitcoin once they heard negative or positive news. Some us, tend to believe easily what media tell us but some of the news is manipulated. The news might affect the price of bitcoin but not too much to totally change it.
