To be honest, ETH is replaceable and the only reason for people to buy it is for investing into ICO. But ICO market is dead and not going to recover. So I couldn't think of a single reason for buying it. While the supply is increasing from the mining activities. I think ETH will stabilized at around 30 in 2019 before the next bull market.
Shit coins like Tron, Qtum, NEO will go to zeor for sure.
