actually, we need a more realistic view of the whitepapers we read.  For example, a project is expected to achieve 1 million users of their exchange in the first quarter and is estimated to bring big revenue and will buy back tokens.  Investors should then pay attention to the members of the group and the traffic index of the website visits, it will surely tell the distance of reality and roadmap.  This is one of the things that needs to be reviewed before making an investment.  The whitepaper is really important to identify the fraud project and the real project.
