$BTC/$ETH market cap ratio = 4.25

$BTC/$ETH ETF flow ratio = 15.96

$ETH ETF needs to get 8 billion USD worth of ETF flow to catch up with $BTC in terms of ETF flow based on market cap

Why is this bound to happen?

Investor with long term horizon do not take directional calls on individual investments. 80% of investments are made based on market capitalisation. Market capitalisation based investments must invest more in $ETH in the future to make up the difference between ETF flows of the two assets

$ETH will lead the next leg of bull run, recent ETF flow suggests catch up trade has begun
