I agree with your opinion, that it is still not too late to buy ethereum. However ethereum is one of the coins that has great potential for long-term investment. By investing now, who knows we can see ethereum's glory at the end of 2017 yesterday and now we can get a profit of 3 to 4 times what we invest. hopefully
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
In my opinion, the increase in ETH always goes hand in hand with BTC even though there is a discourse on launch of 2.0. When BTC moves up other altcoins as well as ETH and I hope the price better going forward.
