I'm missing something.  The whitepaper only talks about the protection of the MN investor's ROI, the structure, and algos involved.  But what is the coin used for?  If I am one of the exclusive 100 MN owners, but no one uses the coin, then I've just added another MN that is building up coins that aren't used for anything.  I already have a Prufus MN, don't need another one.
