ETH miners seems like a cult group who love to see the outricious gas fee the network, despite all the upgrade and forks, gas fees still remain rediculously expensive. The market that ETH would have been controlling alone has already been shared but a total defeat is not clearly visible because of first mover advantage, continuous development of the network and massive offchain support, it will be difficult to display ETH from number 2 position by any competitor.
Acceptance of ETH by a wide number of organisations and it's popularity alone can make it outstand in the market. Other coins except BNB aren't even close to ETH in terms of development of the project and also support.
Other than BNB I guess there is no second alternative to ETH currently, maybe there would come better projects in the future that can take the place of ETH in the future.
I am not sure that ETH could be defeated at all. Not because I believe one or the other but because gas fee could drop at any moment, it is not a forever thing that the ETH gas fee needs to stay high, maybe in a few months they do something new and the gas fee would become under 1 dollars, is there a guarantee that they won't?
I am not saying that they will do it, I am just saying that the "threat" of it being there is good enough for most people to have that type of situation. Which is why I really care about the current situation as it is and will probably stay that way. Sure other projects are not close enough at all, but the fact that even if they get close in development, there is a good chance they may still be lower.
