This is not a perfect name. It is precisely because Ethereum is the king of the altcoin, so when the cryptocurrency market declines, the price of Ethereum is the most declining. It has to withstand more pressure and it creates countless bubbles.
What OP is saying is just based on his opinion because so far, ETH was not able to hold its spot, it has decline and XRP move into the top spot
for altcoins. Everyone should believe what they think is right but it's not debatable anymore if which coin is the king because the whole market is at decline.
