It is not too difficult in my opinion to find out whether the projects are real or fake, the first to follow all the social media they have.
how do you judge them by their social media accounts? the number of followers? number of likes? number of activities? you can't really tell if the project is legit or not by their social medias. What only those can give you is a glimpse of the truth whether they are fake or not, that probably gives you just a 5% hint.
If they diligently explain their projects and actively answer questions, it is almost certain that the project is real.
Nope, scammer could also do this too, they can actively engage with their investor on every channel they have and still scam them for the very reason, money.
to make sure that the project is real, by examining the team members of the project in detail.
This may do for clearing the project since the legitimacy of the project members should be in tact for the position they have in the project. You would not want to invest on a project handled by a guy just smiling on his profile without any academic background.
