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.
