This is absurd. This is anything but a documentary. It's an impressive piece of propaganda, but to be a documentary it needs to be more than "These bitcoins are the solution to everything and they will fellate you in your sleep"
I don't think you understand what a documentary is. Documentaries are SUPPOSED to have sided on something and have an opinion.
