You aren't serious are you? What makes you think it could go this high even in 2019 not mentioning this year. ETH will 'maybe' return to 500$ in december of this year.
This is only expected from the end of 2017 when the market is at a very high level. So can not blame him. He is probably shocked when ETH is only 300$. And the price he expects at least the next 3-4 years can be achieved
