Everyone have his personal approach concerning the most promising ICO projects. But in common there is many points can help you to see and distingue if the ICO is having good potential or not. The whitepapers, the team behind the project, the roadmap, the concept, and the security of their site..
Agree. I believe that it is as hard and controversy job as any other analytics. So it is interesting to me whether there are any good sources how analyze ICOs very precisely. And again thank to everyone who responds 
I've done the analysis including reading WP, looking at the team and reading the roadmap and all look good and great.
Maybe it's a matter of achievement and target, dev is too ambitious.
meaning the project must be reasonable and not greedy. it's important to see a great team.
Did the team engage with you? I invested in Latoken and was quite worried about the project until their team answered my phone calls ahha
