Analyzing an ICO that will be a success and not a difficult thing, because usually there are some serious ICO but in the end they do not have good management so that their project stalled. For me the most rational benchmark is I see who the members of the team who are members of the project. When a project has a qualified team I will be sure, because basically someone who has a high level of trust and quality will always give the best and they will be responsible for their commitment.
