The developing community behind ETH is huge and once most ICO projects have sold all their ETH that they received in 2017, I am sure we will see the price rise again.
of course Ethereum can growing up again, but not in short time, market and whales need time for growing Ethereum price again before hit the top price like in 2017
Indeed, all of that requires a certain amount of time, but after all, the cryptocurrency is difficult to predict, of course, so we can't know for sure when the ethereum price will rise and I hope it will happen as soon as possible
