Believe it or not, you don’t have to be a CPA to start bookkeeping. Just sign up for a bookkeeping course at a community college or even online (such as this course from The Accounting Coach). Once you complete a course, you can start earning, and the median salary is reportedly $34,000. (Some stay-at-home bookkeepers I've spoken with personally make more than $70,000.)
Then the other thing anyone at all could make money from online is just being available for User Testing gigs and great places to look are places like Upwork or Fiverr. Upwork and Fiverr are two giant players in the freelance world . And by far you would be shooting yourself in the foot to not know how to earn money from working from those platforms.
Robo-advisors are diversified investment accounts that are automatically managed by a computer algorithm (as opposed to a human money manager). If you want to invest, but don’t have the money, or don’t want to invest with a money manager, robo-advisors are for you! Robo-advisors make investing easier—and cheaper—so they’re perfect for new investors.
