without bitcoin there is no Ethereum, I think there really is no need for competition between the two, everything is equally good it's just that it still has drawbacks, especially in ETH and BTC about transaction fees which are a little expensive
there will be no competition because the difference is so vast that there is nothing to see in competition, it is true as you said there is no Ethereum if there is no Bitcoin how is it possible for Ethreum to compete with Bitcoin. it sounds a little strange, if ETH competes with other Altcoins it is very reasonable, competing with BNB LTC or other coins, not with Bitcoins.
