if indeed you believe etherium can experience a high price increase like before, it never hurts to save some etherium, the current price is still cheap in my opinion, because it is still around $ 300, just waiting for the current price to survive or not, usually if the price is already at above $ 300 and difficult to $ 400, there will be a price drop, because etherium has experienced such price increases several times
This time I thought a little different, Ethereum will release their Tesnet soon, so maybe that moment can make the ETH prices go up if tesnet succeeds. And also currently the Crypto market is in the Bullish period, so for coins like ETH and other coins in top 1-20 I think it will continue increase if the Bitcoin prices continues to rise.
