What’s the most “passive” income stream you’ve actually seen work?
I feel like most things marketed as passive income are actually just businesses that require a different kind of work.
So I’m curious about people who are actually doing it:
What income stream became genuinely low-maintenance after the initial work, and how long did it take to get there?
Could be affiliate sites, digital products, SaaS, investments, content, rentals, or something completely different.
