Some crypto has intrinsic value, albeit relatively low intrinsic value right now. But anyone with sense can see the potential for a future where crypto has very great intrinsic value, which is part of what drives demand for coins that aren't BTC.
Crypto has value above and beyond a simple store of value because it's linked to blockchain tech, which can provide numerous benefits to companies that know how to utilize it. Companies are just starting to realize how many ways blockchain can benefit them, from reducing overhead to increasing efficiency in just about every facet of their business.
Take VET for example, which helps companies track supply-side logistics. You can use the VTHOR generated by VET to fuel your use of their blockchain to help you become more accurate and efficient with your inventory management. Similarly, you can use the various coins and tokens in DeFi to help run your DeFi apps.
All this stuff is absolutely in it's infancy. We are just getting started. Is it possible crypto dies on the vine and never expands beyond the relatively narrow scope of uses it currently has? Sure. But I'm betting that it won't die on the vine and will instead be a fairly ubiquitous part of life in the near future. And a lot of people much smarter than me think so too.
