Coinmarketcap marketcap have little meaning. On that list are all kinds of cons, tokens securities, ... Everything and they simply cant be compared. Bitcoin can have 15 dominance but that would not change anything. It would still be most used currency. On CMC coins like Bitcoin are Litecon and then Monero. BCH And BSV are also same, just that since so many did not claimed the coins its marketcap is way to inflated. The rest are non mineable or were started in ICO. You cant compare something that is made while burning electricity with something that they just print few billions.
