Hod do we get from this:

                  Around 0.2% of people (10-15 mln) using Bitcoin
                   80% of coins mined.

To 100% of people using bitcoin.

Is 98,8% of all people supposed to only benefit from the 20% of bitcoin left? Be left at the mnercy of the 0,2%? Other than that,  in the end it will be so difficult to mine that if cryptocurrency was to become a global thing, mining would take a significant portion of world electrical consumption.
