Ethereum just scored a new ATH since January 2018.
IS Ethereum still worth it tho?
Taken from Binance

I want to correct your opinion, because the ATH price for Ethereum is $1,432.88 (Jan 13, 2018) and now Ethereum hasn't reached or even made a new ATH, so of course Ethereum is still worth it to investing and get profit from investing in Ethereum.
