It's not easy to predict whether an ICO will fail or pass.
ICOs like Rentberry bring the ideas of long-term leasing to the blockchain and MeVu brings the idea of a great blockchain visionary application using the basic blockchain algorithm in a new and innovative way.
Usually, the problem with ICOs is the fear of people thinking "will they actually follow up on these ideas?", or the commitment of the team to the project. To me, pick teams that are transparent on social media resume sites etc and this wont be a big of a problem.
