I don't understand people thinking facebook is small. Dudes are running a website that has over a billion people on it even if you do not use it anymore, an app that people chat everyday, literally almost all mobile phone users use whatsapp (except places like china where it is banned) and a website where millions of people share their pictures and write comments all day. So they are one of the strongest technological companies in the world that is literally gaining power like its nothing over people and doing the "big brother is watching you" part of their work for the governments and whoever else pays them.
So, thinking that globalcoin is not a big deal is really naive, it is a huge deal, its good that crypto currencies are getting famous but globalcoin will be used for many bad stuff because facebook has done many bad stuff with the power they have and now they will have another big power over people. This will be horrible.
