its very difficult to identify a shitcoin.. they are hiding 
even after so many research you do on that coin still you are not convince that is a shit coin..the moment you realize its a shit coin is when you bought some and afterwards its has no more value
You're right, I did research on the project for almost 2 days just to find the information I needed, but when I joined IEO they turned out they were shitcoin .. in my opinion real projects and scam projects 90% have in common and are very difficult to be detection even after so many research you do on that coin still you are not convince that is a shit coin..the moment you realize its a shit coin is when you bought some and afterwards its has no more value
