I think we need advertisement across the globe and mainstream media for BTC to proliferate and be adopted by the public. All of bitcoin's features should be spread by the media and not just the negativities and rumors. The technology behind and how it works should be understood first before the public place its trusts.
You are mistaken we cannot rely on the mainstream media to advertise bitcoin they are bought they will do whatever they are told to do, they are not going to promote bitcoin and risk their careers and their source of money just to promote something like bitcoin, this is why promoting cryptocurrencies in social media was important but now that is not possible either with the current bans.
