Monero is one of the few chains that offers a truly new feature on top of other alternatives and... look at the price chart of its tokens. Now compare that to Shibe or whatever. Makes it pretty clear that price is driven by memes rather than features.
I think this is very true even outside of crypto. As an extreme recent example, consider GameStop.
This problem is larger than crypto. It seems to be related to the accessibility of trading to "retail investors" (enabled by lower fees, new technology, monetary policy, etc.).
