CFA and CPA are not really comparable (even though they're both 'finance'). A CPA charter is closer to a JD degree / bar exam in that it is the necessary entry requirement for a legally defined profession (with quite steady demand). A CFA is more like a Master's in that it can help you get an interview for financial analyst jobs, but it is neither necessary nor sufficient to work as one. But it can help a great deal, that's true, especially when you're transitioning.

Also, those are some pretty serious things to do as a hobby.
