Actually, it's quite difficult to identify whether it's a scam or not from the start. But at least, maybe some of these events can start, like looking at their team profile, whether it's really real or looks fake. Of course, social media might be quite helpful at this time.
and what often happens is that scam projects are usually to good to be true, so just be careful if you meet a project like this. and analyzing the authenticity of the WP, this might be more difficult and time consuming.
ah, actually, if you're afraid of scam projects, why should you get involved with new projects? why not just focus on old projects whose coins are already listed and have good market caps and values?
