I personally don't wait any ATH from ETH in the mid-term. Ecosystem has too many problems that must be fixed before any new expansion. And earlier ETH grew with ICO wave. But whta today? STO and other idea? I'm sure it will not so wide application as ICO
Yes it can but it's really hard to tell when. Everything is possible in crypto market so I won't be even surprised when it happen. I will be surprised if it won't happen.
I think that there are many prerequisites for active growth of ethereum. I would not be surprised if in 2019 we will see another maximum of prices for ethereum. And this is all thanks to Cosmopolitan and the scaling of the block chain.
Sorry, man, it names
