Hello!
It is actually very hard to identify a scam ICO project.
You could verify of course the team, the whitepaper, theirs accounts on social media....etc, but in the end, the project still could fail or simply the team could scam you.
My personal measure is to invest as low as possible and just wait for the exchanges.
In order to invest, PLEASE
do your own holy and blessed research.
Best of luck!
