I had read an interesting way to make sure the project is real. You can identify the project is fake by it's address of the company who is running IEO/ICO. Fake project would be indentify with this way because they put fake location. You can check it with google maps to verify if it's real.
So how do you indentify if the project is fake?
Honestly, I don't know about this tecnique since we are only checking the people behind the project if they used fake Linkedin account or stole images from the internet. now this tecnique can be countered by the scammers but sometimes they can be track by this method. Yours are different but sometimes it would be an easy method to know if the project is scam or not.
