This is only the beginning. It will gain more value with time. 2018 will be the year of ethereum. Im expecting a 3x or even 4x at least.
I was also having this expectation few months ago and thought that ETH will be near 4 figure mark in price . But we saw what is happening with ETH. BTC is jumping too quickly and ETH just sustaining itself at the near about same price and not rising with the pace of BTC. Just not sure for 2018 abut this coin for now.
