Let's take Steemit for a minute. It has failed, why is another story, but it is failing to deliver. (If I were to stick in a short explantation it has to do with governance, vote buying, and failure to properly reward good content.) And then we get to the exchanges, there are too many of them and they are all faking volume. And then you get to the projects there are big ones that are legitimate (BTS, EOS); but there are big ones that are not, -BitConnect, Tron, ect. If there are not real projects, trading those projects do not have real value. The Idea that a decentralized organization could revolutionize the world is like communism, it is a great idea it just never works. It can work for a while or with the right people or under some circumstances -like when there is other peoples money to steal- but is lacking.
