Its impossible to ETH to get back to his ATH or even hit another ATH.
Lets be realistic that year that ETH make his price up to 1400$ is the season that people think that ETH make thier own demand by having a platform that can create a token and use ETH for gas.
that year any ICO created is so hot that not even  one project failed to raised fund needed to start the project. But this year is different and even investors lost trust to eth for having many shit scam token using that platform.
