If you're looking for ways to make money and aren't concerned about legal risk or ethics, certainly I'd expect hacking to be on your list of possibilities. There wouldn't be so much hacking going on if it wasn't lucrative.

It actually isn't very lucrative.

Some of the crypto-blackmailers use public bitcoin addresses, and they don't get as much money as you'd expect.

For the fact you'd probably have to move your life to Russia to escape the FBI, it doesn't pay very well.
