Go to Binance wallet, top up alpha coins with around 1200u, and daily mine alpha coins on the BSC chain such as b2, zkj, etc. This way, you can earn 16 points daily; after a few days of mining, you can claim the airdrop. Generally, around 200 points is sufficient, and the points required vary by project.

Airdrop claim path: Binance homepage - News - Alpha event, where the rules are also introduced. You can check it out yourself. You can add me to your community; first, add me to my Binance chat room.
