It's better than dividens... 20% of all money that it's going into platform will be used to buy ICN, so Iconomi will have constantly demand from their platform

After burning all the "ICN" tokens except yours.

imagine that you are the only person who have the last icn token in the world,
and the platform is obliged to buy it from you(it will provide 20% ( may be millions of dollars) from its net earning.) to complete the task of burning .
logically you will be a very very very rich person.
so the patience is the only key that open this treasure.
