I agree with most of it, but it helps to understand the concept of "coins". A coin is both a unit if a particular currency and each currency within the overall Cryptosphere. Without lots of coin a cryptocurrency will die from lack of use and without lots of sub currencies evolving within the Cryptosphere the whole will suffer a lack of innovation and ultimately lose the battle to centralization and just like a dying star implode into a black hole (private esoteric network without a mainstream use).
