Everything is possible in crypto currency but no one knows when it will reach that value.I think ethereum will reach $2.5k by end of 2018.Ethereum price growth is slow because of its unlimited amount so we can't compare it with other cryotocurrency price change they are limited amount.
No ETH can achieve such prices, currently their prices only fluctuate at $ 800-1000 can not be higher. So do not be too high expectations, you will fail, give a moderate goal, do not greed
