I'm sorry to burst the bubble for you but there's no such thing as passive income that is truly legit that I know off. Perhaps you can offer loans here in the community in this section: Lending, and that's the closest thing you can get passive income, but it can be dry for months or you can have many people availing of your loan services. But everything has risk, just be careful of people who you dealing with, specially newbies or people getting a loan without any collateral.
