Earning on Binance without deposit, investment, trading, or referral is extremely limited. However, here are short legit options:
1. Learn & Earn – Complete quizzes after watching crypto tutorials (when available).
2. Airdrops – Occasionally offered for free by Binance or projects listed there.
3. Giveaways – Join Binance's official social media contests.
That's it—most earning methods require some action or capital.
