The same can be said about Bitcoin, most altcoins and even fiat money. ETH isn't the best altcoin ever, but some altcoins aimed to be "ETH killer" weren't performing well.
Except last bullrun bitcoin was $18000. Eth was $1400.
Now Bitcoin is $35000-42000 and Eth is $1400.
ETH was down to $70 at one point as BTC was still $3800. Lol.
