In past we found that when ETH/BTC pair moving in market most alts are performing very much and sentiment of alts looks like a bullish. Most of coin btc pair does not perform as expected still but once it's start to move to upper level the alts can give breakout and will see the massive move in all coins.
I'm accumulate the btc pair of L2 coins for better returns bcz once ETH/BTC pair start the rally the more volume can seen in L2 coins like OP,ARB,ZK,LRC,IMX.
let me know your favourite one.
