We have etherum bossing altcoins since time past and there has been non replica of any coin that has tried bossing etherum
Just like bitcoin is a king on its own, etherum remains a king on its own too.
Looking forward to the influence of bnb tokens, and okb tokens can have on etherum dominance.
Ethereum is the king of the erc20 tokens, not the king of all altcoins I think, although it is true that currently ethereum is still superior to other altcoins but they are on different paths. And it is not impossible that one day Ethereum's competitors will succeed in beating Ethereum in the market.
