Carrot is a company that pays small amounts of Bitcoin for completing different tasks. You get sats in your carrot app and then you can withdraw them to your own lightning wallet. You can also read Bitcoin Magazine articles directly from the app to get some free sats as well.
Recently they created a new site, Carrot Courses:
https://courses.earncarrot.comThey currently have one active course:
Intro to Bitcoin: A friendly introduction for Bitcoin beginners to earn their first bitcoin.
But they're planning to add more:
The Bitcoin Ecosystem: An intermediate course exploring Bitcoin's various participants and technical properties (coming soon)
After you read the material and watch the videos, there are some quizzes. If you get at least 90% correctly, you get a few sats.
Here's an example of the type of things being presented in the Intro to Bitcoin course:
This might be something that helps educating the population in general in an easy way, and also they can get a few sats for free while doing so. Also, more advanced courses coming in the future might be interesting for bitcoiners.
