Very solid market-based response. Milton Friedman would have agreed. Just a small tweak. Even though everyone says it , it is not “survival  of the fittest “....it is survival of the fit. An entity is either fit to survive or it is not.  So there may be more than one entity that is fit.....you believe that it is just about a sure thing that Bitcoin will survive. That does not mean that IOTA won’t.   By the way , your explanation owes more to Adam Smith than Darwin.....and I might add nothing to Karl Marx.
