What was your best passive income in 2020?

I have made a few iOS apps (Cone[0] and Unwind[1]) which generate enough to pay my bills.

Low cost index funds provided a 16% return in 2020 and require nearly zero effort.

While not entirely passive, I developed a SaaS[0] to scratch my own itch. As a freelancer I often use Asana[1] with clients but one serious missing feature is easy referable task IDs like Jira. (e.g. HN-123) Furthermore, having git commit messages as notifications in your tasks is also a really nice addition. So, meet Astogi[0]. Currently it isn't replacing my freelancing (yet) but it generates a small decent income which is for a big part passive.

My best passive income is probably my day job, my investments require a lot more focus and time.

Lol, guys, it's a joke.. kinda.

Meme stocks. Was up 100% for the year but settled down to 45%. Will continue memeing until the end of the year. Meme profits got rolled into more legit stocks (usually just to hold profits with a possibility of some upside until I can buy a good dip), but yeah, mostly stuck to trends and bets, no real investing.

Also lost money, but I memed my way out of it somehow.

Google was up about 30%. I made most of my money by procrastinating about diversifying.

(I believe in diversifying for the usual reasons and sometimes do it, but usually regret it in retrospect. Maybe someday I won’t regret it.)

It looks like I will regret diversifying again this year.

I run and develop the trailer booking website for my fathers company. I earn based on the number of bookings. For some reason (possibly COVID) a lot of people moved so it was a very busy year, which means I got a nice little side income.

I'm about £6 up from crypto

Ethereum DeFi yield farming. Will be migrating funds to ETH staking soon for a nicely appreciating yield-bearing asset. Tips and MEV rewards will be the icing on the cake.

I wrote a weird psychedelic road novel (my girlfriend describes it as The X-Files meets Big Lebowski) It makes me a couple bucks a day.

A mobile game I built in a few months last year: (Android) https://play.google.com/store/apps/details?id=com.reckoning.... (iOS, newly released) https://apps.apple.com/us/app/sandbox-city/id1512598054

Brings in around 400 euros a month from ads and in-app purchase revenue.

I have talent in dev/code, but didn't use any of it. 2x Corona, short-time work, depression.. :(

I'm fully open for any suggestions.

It's not passive: I started investing into stocks and sold almost all for about 5% profit in total. I think many won't like it, but I used that money and invested into different cryptocurrencies. I ended up with about twice my total investment and on some days I earned more per day, than monthly with my dayjob. The goldrush wasn't forever though, because after may I'm back to my initial investment.

I made https://extensionpay.com, a service to let browser extension developers easily take payments for their extensions.

But I feel like making a SaaS isn't really passive income — it's flywheel income. Takes a lot of up-front work to get it spinning and then requires a little effort here and there to keep it going.

Selling few delivery plugins for woocommerce/prestashop was a really nice idea at the time which did not really work that much before pandemic (for ex https://codecanyon.net/item/stuart-for-woocommerce/25673890)

Domain names, sales and traffic (PPC).

Traffic (PPC): Approximately US$ 10K a month. You have to have names that have type in traffic.

Sales: Not truly passive as we do reply to inbound inquiries and manage a sales pipeline. It's highly lucrative if you have .Com domains that businesses want.
