By the way, I think we could get a better measure for a coin's "popularity" or "value" than "market cap" if we try to measure its transaction activity. Probably Bitcoin's "dominance" would be much higher. Coinfairvalue tries something like that, but has some pretty strange valuations ...
That site lost my interest instantly the moment I saw BCash's "fair" value is $900 instead of the current $500.
It enjoys way less use, is a coin donated to people for free, is artificially being kept at a certain value to not have miners ditch them and make it easy for malicious entities to attack its network, etc. It's probably safe to say that they aren't really that keen on Bitcoin.
It's way more useful to put coins aiming to operate within the same industry each in their own dominance list, which would significantly change things, but since this is a mere noob metric we probably don't need to take it that seriously.
