The devil is in the details: you can read mises.org and get a sketch of Austrian econ, but in most cases you'll just be regurgitating other people's conclusions -- it will be a surface-level understanding, no better than any other surface-level understanding of anything.
Which is fine, not everyone can possibly have a deep understanding of more than a couple of things. The annoying (and harmful) thing is when people think they understand more than they do. Empty bitcoin talking heads are no better than empty talking heads in any other place. Unfortunately bitcoiners are no better at understanding this truth than anyone else is.
Anyway, Human Action is a giant lift and rewards investment. Doesn't mean that lesser investments in other places aren't a better use of time for some people in some circumstances.
