Cash mining? This isn't the good old days anymore unfortunately, OP. Even faucets which is another way to get some Bitcoin are not worth it anymore unlike back in the days. You would be better off day trading or long term holding rather than pursuing these sort of "generators".
Maybe start your "online content creation" in Youtube first, monetize it, then invest those earnings in crypto or possible a mining rig if you are after mining by your own. Can't give you further advice in Mining since I have not done that yet by my own.
