It would be great for bitcoin to promote it self on social media because a lot of young people use social media this way a lot of young people can start in bitcoin and bitcoin can also grow you don;t only need Instagram maybe they can even use Facebook or snap chat to promote themselves.
I think Bitcoin has been promoted to other social medias like facebook because I sometimes see the
BTC around facebook. But I do hope more people will share their knowledge about Bitcoin, not just on Social Medias but starting with family and friends and help them motivate too.
