Ethereum has never been called a sinking ship, it will only become once people are abandoning the chain and projects are moving to another chain, but it's not the case so far, they may be quiet right now, and that includes the price but not for long, they are still on target once Ethereum POS start moving things are going to change.
The only reason why I continue to believe in ETH is a successful update that took place at the beginning of this year. All 2019 I was sure that this project could not continue to exist and I was waiting for an update. The update was successful and they did not move the deadlines, that's why I did not sell all of my ETH immediately.
