I will still choose to save more BTC than ETH, especially if I have BTC first, then sell BTC to get ETH isn't something I will do, one little thing that is unpleasent in ETH is the fees network high and this could be the reason crypto lovers to leave ETH.
actually it's better to just store bitcoin than etherium, but everyone has their own strategy to get a profit, it's possible that people who exchange bitcoin for etherium believe etherium will increase again after this, and of course they will swap back if they get a profit
