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.
I completely agree with you Ethereum is the future of the crypto industry, I believe that this cryptocurrency is the future on the planet, but the price of course fluctuates and is not as great as that of bitcoin, but still the ether is the king of altcoins, because all possible payment transactions are involved on it for gas and also buterin will not let such a cryptocurrency die once, it’s not for nothing that he invented it
