You mean to say: how do we know if the project that am dealing can be real, genuine or just another scam fake one? Well, we have to understand that it can get hard to really know and determine the authenticity of the people behind the project because most of them are scam artists so they know how to hide their tracks. Now, there are already good teams that are so willing to pass a KYC team...meaning the whole team submitted their verifiable information to a third-party accreditation and they are also making sure that the whole project is audited by a a credible auditor. Unfortunately, only a few projects are willing to do this. So the first thing you should do is search all over Google to find anting negative on the project and the people behind it.
