The media is just one arm of the mega wealthy parts of society. A lot of these mega wealthy people or corporations recognize the danger that bitcoin is to them. Bitcoin can topple the entire banking industry in a decade or two, maybe not bitcoin itself but blockchain technology in general. They can see the writing on the walls and it scares the shit out of them. The same is true of governments, you can't really stop bitcoin though, there's no point of attack. Anyways, that's why the media is negative about bitcoin. The same people who own the media own the government and banking industry and flat out, bitcoin is a threat to their status quo.
