Ethereum fate will very much depend on its developers. They must have time to create Ethereum 2 before its main competitor, the BNB gain momentum. Also Ethereum growth is possible if you start a new alt season. But when it happens, nobody knows.
Vitalik Buterin and his team will definitely bring his crypto project and altcoin to a new level of technological development. However, Ethereum 2.0 can be launched only in 2020, therefore, we have to wait for these changes for months. It will be now better to hold ETH and do not sell it: finally, the price of the altcoin will go to the Moon, and we need to be a bit more patient.
