When deciding portfolio composition for ETH, I looked into its associated betas that historically showed upside reflexivity. $PEPE, $LDO, $OP, $ARB were the OG 'kneejerk' ETH betas of old.
I ultimately decided to stick purely with ETH as I suspected a large component of marginal buying would not come from natives but instead TradFi. So far ETH ETF inflows have hit record numbers, and ETH betas have by comparison barely kept up.
So far, so good.
