I think this is all insane!
Computers were a thing of science fiction not but a half a century ago.
Computers all being linked together and talking to eachother, that was the stuff of fantasy!
And, I will agree with your premise, that looking at actual use rates is better than market cap.
(should BTC have such a high market cap, since satoshi has never touched his coins? They are not part of the market, so...)
However, looking into the future, we must realize that all of this is code. And just like steem moved to the latest graphene, all of these other coins could completely change their block working algorithms almost overnight. And so what holds today, may not hold in the future.
It's the wild Wild West in crypto but on the other hand fiat is WAY more insane with it fractional reserve banking, quantitative easing, bail outs and bail ins! We shall see what happens but for certain there are NO guarantees.
