1. I believe everyone remembers how Worldcoin surged from $2 to $10 at the beginning of last year, causing many to leave the space. Recently, I discovered a similar early project to Worldcoin that can be earned for free called Billions. Billions is a digital identity verification platform that provides trusted identity verification services for humans and AI agents using zero-knowledge proofs.
2. The reason for following Billions is that it raised 30 million dollars, with investment institutions including Coinbase Ventures, Polygon Ventures, and other prestigious institutions. Projects invested in by Coinbase indicate recognition from North American institutions. Following big institutions to earn rewards can yield some benefits, after all, big institutions aren't short on money.
3. You can completely earn Billions for free now. Besides needing some time for initial registration, afterwards you just need to spend a few seconds daily to check in. Our goal is to earn points, which can be exchanged for airdrops. Below is the tutorial on earning Billions for free.
4. Open the official website signup.billions.network?rc=CB3GED6O with Google Chrome, then click "continue with Google" to log in with your Google account.

5. Enter "BILLIONS500K", then click "apply" to earn points.

6. Complete various tasks to earn points.
Daily Check-in: Just log into the website every day and click to earn points.
Download APP: You need to download the Billions app on your phone, then log in from the app.
Verify Human: Requires face scanning on the mobile app.
Verify Human with an NFC-enabled phone: You need to use the mobile app to scan a Chinese passport.

7. This is the complete tutorial for Billions. There are many tasks, and you don't have to complete them all at once. It is recommended to at least complete the "Daily Check-in" as it is the simplest task. If there are any unclear points, everyone is welcome to leave comments for discussion.
