As we all are seeing the launching of new projects one after one. So, one should take care of many things before investing. How to know the real potential of these new projects?
To actually see the real potential of certain projects are when they hit the exchanges and could actually survive with thousands of coins out there competing. New projects have different ideas and roadmap to do with their "competent" team on their thing but still if they can't make it real and just the BS on whitepaper then it's not going to work, because so many projects have done that.
The only thing that matters when they hit the exchange and then people will start actually looking at it.
