No matter how much ETH costs, it will always be considered a very promising crypto coin for the next couple of years, the most important thing is to invest in ETH and sell it on time.
The changed percentage of price since ICO shows how weak the development is. I doubt the price recovery will happen soon. There will be several attempts by bulls to squeeze the short side of the market but the bears are strong side too. My prediction is around $600 for next year.
