Yeah, I read that and it quite caught my eye that many of these social media companies and owners don't exactly understand the principles behind an evolving and fast pace technologically driven market like the cryptocurrency. There isn't a bubble anywhere.
To be honest I do not believe that a company like Facebook does not understand exactly what cryptocurrencies are like.
Maybe they do it because they understand it too well and they see it as a treath.
It is a matter of privacy or business related matters but for now i still can see those crypto and ICO ads nowhere an is sponsored to be shown publicly. Facebook is not the only social media that we can rely on but it is a good example for advertising their ICOs and there is a lot of social media has been used since everyone was using Facebook before. I guess a lot of complaints about of the scammed ICOs and it brings a bad reputation to everyone.
