tl;dr conclusion from the article: "Filecoin’s economic feasibility is hard to predict and, given a simple summary of risk related points, the biggest hurdles are probably going to be acceptance from the users. In addition, Filecoin shows certain characteristics of a Ponzi scheme but the trust built by the team members in the past leads us to believe that it is not one. Filecoin’s Whitepaper introduces novel concepts and predecessor projects by the team members which prove their technical capabilities. Hence, it appears that Filecoin is poised to be an outstanding project although it remains to be seen if it will be adopted by the average cloud storage user."
