Yeah social media nowadays is the source of fake news, fake events, fake people and etc. I have the empathy of this post since I am also a social media hater like facebook. But there different ways of viewing things in this social media. One could be affected by theses events or one doesn't care of what is happening on social media and focus on what is the advantage of these application. There lot of advantage with social media esp. facebook. It is a matter of how you view things regarding with the issue. Just ignore them and focus on what you can learn more with social media.

For small scale I agree but not large or national in scope, this is because the user is still small and not bitcoin dominates the internet payment system, need more time to proof bitcoin can reduce unemployment.
