Before the last bull run ETH stayed around 300-330usd for quite sometime If I remember correctly, and looking at the steady climb witnessed on the last few months, added to the pending changes/possible improvements on the project, I would not be surprised to see it there any time soon...
let's hope it does, ETH is one of the crypto world engines
indeed, all we need is only patience for now
because, in my opinion ethereum price will go to $300 in the near time my friend
