ETH is indeed the king of Altcoins and BTC is the king of Coin / Altcoin. For ETH itself Investors have never had any doubts about ETH even though its value is currently declining and that is reasonable in my opinion because it follows developments in market values. This is not a problem that means eth holders because they know the performance and potential behind this Vitalik coin will definitely rebound and ATH will return.
everything will be the same as what you said, that it must be admitted that until now eth is still the best for altcoins, and always gets its portion, even though there are many good altcoins, all investors still hope for eth until now. it seems very difficult and irreplaceable, although maybe BNB could very well become eth's rival in the future. if bitcoin improves, then you can be sure that all the best altcoins will also follow and it's not unusual and so far it has been like this, when bitcoin reaches ATH it will also be followed by the best altcoins.
I am interested in your statement saying that BNB will be ETH's Rival. My view is still very far. BNB's younger brother, Eth, is unlikely to quickly overtake ETH's position as the King of Altcoins, even though it has a large number of users. Investors are now very proficient in determining their long-term investments. The choice is exactly the king of coins and the king of altcoins.
