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.
To be honest so far Ethereum is our second choice for investing apart from Bitcoin, Ethereum is the right Altcoin if you want to invest considering that Ethereum has very good quality so far while it is in the top Altcoin, and we are at least relying on a declining market to continue to earn Ethereum because of this we think is very good.
