Ok- so, in general, businesses don't hire low or mid level staff to jump on a bandwagon like crypto or AI. They hire leaders or expert consultants. This is a super frustrating trap that many many junior people fall into.
If you are junior, and you learn something specific in a domain, you can maybe be hired by a startup focusing on that specific thing. But that is tough to do without context. Many interesting/exciting technologies don't in fact have a useful business purpose. And "AI" or "crypto" are not specific enough, there are hundreds of potential specialities in each.
To get some context on specific technologies might develop business utility, try the Thoughtworks Tech Radar. Go through the trial and assess categories going a few years back, see what has matured into adopt and what is on hold. The Radar is specific. Each item is a specific tool, technology, or practice that an individual person can build expertise in.
