What are some ways that someone can (theoretically) make a monthly income

This is only a hypothetical question, as I am looking for crypto-related ways that someone can make a decent amount of money every month. I'm not actually looking for any crypto-related income, I would just like to make some posts about this to put some things in perspective.

For example, last month I looked at how many moons someone would need to earn to make the equivalent of the US minimum wage. Are there any ways someone could do this?

Last thing I wanna mention is that the obvious "get a job" isn't what I'm looking for. Any other ways to hypothetically make some money work, so any ideas or suggestions are welcome :)
