market-cap and dominance can be skewed and inaccurate.
Complety fake
What does that even mean? You measure market cap by multiplying amount of available coins by their market price - which of these 2 elements is fake and for which coin(s)?
Market cap is what it is, the fact that many put way too much weight to it, or interpret it in a wrong way, doesn't make it useless or fake. If adjusted for low or fake volume - it's pretty good metric imo.
your mistake is that you are using market cap ratio and calling it dominance. it is like picking up an apple and calling it an orange! just because coinmarketcap.com is dumb enough to use the word "dominance" it doesn't mean it is correct. in fact dominance in a market has nothing to do with market cap specially when it comes to cryptocurrencies where 1 coin can create billions of tokens out of thin air and have billions of dollars worth of market cap and have a bigger "ratio". and none of that billions of tokens even have to enter circulation for it to have that market cap.
I see your point, but you're talking about 'market dominance' in a classic meaning, related to measuring companies' market dominance - such is simply not applicable to cryptos (as there's no revenue involved). "Dominance" is also a word on its own and can be freely used. It's pretty obvious and clear to everyone that CMC's version relates to market cap dominance only. I see no problem here.
