As long as fiat is around, crypto will continue creating problems to solve to try and maintain its relevance.

I also find that having a solid understanding of the crypto space can conversely enhance your understanding of bitcoin and money in general. Once I understood what doesn't work, I'm able to appreciate what does work, and also have another framework to view things like the US dollar. From a "crypto tokenomics" perspective, you can obviously see how awful the US dollar is at serving the role of money.
