It's better to keep ETH until 2019. If you have money left, then I recommend you continue to buy ETH while ETH is still under $ 1k. ETH is a very valuable electronic money and I think ETH may be more popular in the future
Agree with this opinion. I think ethereum is good coin to hold for long term. Right now, ethereum is number 2 in market cap after bitcoin and I am believe with much supply than bitcoin, ethereum can take bitcoin place as leader on coinmarketcap
