The good thing about ETH is that this is one of the few solid alts that you can hold onto. Unlike most alts, eth is actually doing progress in terms of their developments. I believe Buterin is not just sitting around and not doing something.
So for me, if you have spare, you can stash some ETH. Much much better than most meme tokens or alts. But even if ETH has solid foundation, still it is advisable to keep up with its progress. Even big projects fail without warning. And this is true for all crypto projects that you want to get involved with. You don't just buy, hold and forget. Because most of the time, these alts exit from the market without warning.
Well, ETH won’t quit like all of those scam projects. It has never shown such sign and would not because it’s a transparent project. However, it is still possible for such huge projects to die out. We can see how there’s competition amongst blockchains; how Solana is competing with Ethereum. That shows that if one of them losses grip, they’ll be left behind, which I believe adds to the reason we can see them constantly making updates in codes.
