Ethereum is still undervalued in my opinion. It'll be Bitcoin successor in the future, because ethers are more advanced technically. They are faster, have lower transaction fees and support smart contracts. Ethereum is not also a currency, but also a platform for other services. Thus Ethereum will definitely continue to grow.
I agree with you. ETH is really undervalued yet it has giving us solutions which other coins cannot offer. I have high hopes that the price of ETH will still be growing through time.
