Nothing is certain in speculation mate specially in this crypto market when the volatility is the main reason why the market goes up and down.i think ethereum can break the highest value reached about $1,500 in January 2018 but the maximum is unpredictable.ofcourse not as what bitcoin has which $20,000
if ethereum can run from bitcoin. just now when bitcoin goes down and rises ethereum it looks just silent and very little moving. I'm afraid ethereum won't achieve that. or maybe ethereum is preparing his own pump. it will be very good.
