2. Anonymous project.If you want to scam people, best way to do it is by hiding your identity. Therefore you should never trust a project that does not display its team members, company information nor physical address. No matter how good the project seems, there is a reason why they are hiding their identity.This isnt always the case, I have always felt suspicious of ICOs when they link to the team members linkedin profile. Well, this may be legit in many cases as they want to build a positive trust by showing off the team. But, I also have seen people buying 20-25 old linkedin accounts through this forum.
Actually, there was one project that showed even the personal address of its owner. Sadly, it was still a scam. It's best to check past projects of these devs and their communities to be sure.
