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.
Yeah it is of a truth that ethereum has been dominating the altcoin section for a long time, but I could remember sometimes that Ripple has also tried to overtake ethereum, although this wasn't lasted more than few hours. There are also other altcoins that are doing well, for example Stellar. Ethereum needs to continuing developing/improving, otherwise overtaking is very possible.
