I do not know about 1450 this year,,, I do not even want to say I am confident it will stay above $145. We have seen ETH go up so many times this year in Q1 but fail to keep the high. ETH will recover, for sure. I bought some at above $200 and above $300 thinking I had the dips, but I was proven wrong so of course a lot of people like me want to recover but we should also be realistic about 2019.
Probably a conservative estimates of around $300 is not that bad. The price prediction seems to be very bullish though. But we all know that market sometimes react differently, but to be honest I'm not seeing ETH going to 4 digits this year though.
It all depends on the price movement of BTC, if bitcoin went on another bull run, then it's possible that Ethereum can get closer to $500, but if the market stagnated at least for the next weeks or so, then I don't think that $1450 is doable.
