Yaro, this is a great post! Personally, I have banners and other advertising avenues. I am surprised though that you don’t mention Adsense as it fulfills all your criteria: It is easy to set up, it is totally automated and you don’t need to do anything and it is totally passive.

For those with a large Twitter following, you can make money from your Tweets alone with Sponsored Tweets. You could be paid for sharing a business’s information, recommending restaurants or hotels, or tweeting pictures of you using or wearing products. As with all sponsored posts on social media, businesses will only be prepared to pay you to Tweet if you have a large following that you can influence. So work hard on building up a loyal fan base.
If you start getting too big for EBay or decide you want to try a different flavor, Amazon has a marketplace as well. I prefer using Amazon because I can depend on their shipping, have a Prime account, and trust their reviews (overall, not usually singularly, although occasionally that as well). Learn more about Amazon’s marketplace by clicking on this Lifehack, and delve into the marketplace.
Robo-advisors are diversified investment accounts that are automatically managed by a computer algorithm (as opposed to a human money manager). If you want to invest, but don’t have the money, or don’t want to invest with a money manager, robo-advisors are for you! Robo-advisors make investing easier—and cheaper—so they’re perfect for new investors.
