In the past some coins has shown surprise upwards movement and ethereum been one of the popular coins has shown significant pump in 2017 and early 2018! Will ethereum get to $500 this year even if sec approved ETF?
That number seems difficult at the moment, in the best case scenario I see ethereum reaching a price of 250 to 300 dollars which is very far away from your prediction but such a number will be great for ethereum because it will allow it to put a healthy distance between ripple and itself and will bring back the confidence of the market to ethereum since it has been one of the coins that has suffered the most with the bear market and the lost confidence of investors in icos.
