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?
1. First do research on the pictures of the team, you can use google image search or other image search because some project use stolen pictures
2. Stay away from any projects that use cheap website designs, they are mediocre scam projects
3. Check whitepaper for any plagrism
4. Stay away from any project that gives up too high discount on ICO or IEO
