I'll answer this, even though I think it's just karma-bait.<p>My best passive income is a piece of software I made in one week that processed payments for school events (field trips, clubs, etc). I've made over $120,000 in two years with it.
There is also "Your best passive income? (2015 Edition)" from 30 days ago <a href="https://news.ycombinator.com/item?id=8822151" rel="nofollow">https://news.ycombinator.com/item?id=8822151</a>
<a href="http://www.rippedrecipes.com" rel="nofollow">http://www.rippedrecipes.com</a> My cousin and I started this site a couple years ago, revenue is steady around $250/month, we get on average 4,600 unique hits/day ... reading other people's revenues I feel like we could do better with the traffic we get, so if anyone has any comments or thoughts, they're more then welcome!
For God's sake, these sort of threads pop up every week. No one has a magical formula that you can just copy. There are thousands of ideas in the other 200 threads about passive income. Please just stop... really.. stop.
I have a cellphone site I bought from flippa for 4k that generates from $400-$1000 every month.<p>Tried buying other sites but they were all duds. This one has made over 25k since I bought it.
I build a website (<a href="http://www.iprank.tv" rel="nofollow">http://www.iprank.tv</a>), a hub for fresh and funny pranks, which makes me about $1k per month.
