I've read that Facebook is going to have its cryptocurrency
https://cryptobriefing.com/ready-for-facebook-coin/Since Facebook and Mark Zuckerberg as an entity is highly influential, do you think it would bring crypto in a positive light? I am thinking that it may raise awareness of cryptocurrency as a whole and not just bitcoin.
Facebook actively promoting a cryptocurrency (its altcoin) and Facebook promoting cryptocurrency are 2 different things. If anything, a Facebook linked cryptocurrency will be worse than fiat - you will have absolutely no privacy and you can't shift these coins to any other organization. I really don't care whether Facebook starts its own currency or not.
Alll true but perhaps relevant is that wechat bucks are the most popular cryptocurrency on the planet with ten billion or so transactions per day, so the social media companies still have real sway in terms of what currency we use (we use the worst one we can, Gresham's law).
