I think in the world of economy, inflation is a normal thing, it can come back in the future, and it can improve and the situation will improve again. Not entirely the industry can always increase, there will definitely also be receding. In my opinion, it would be better to maintain the ETH, which is clearly evident, it can provide good results. ADA might also be good, you can buy it for long-term investments, but that doesn't mean you have to sell all of your ETH.
