Binance Chinese Official Announcement of Alpha's Next Airdrop Requirements, where trading the tokens on the Alpha chain will qualify for the airdrop.

Airdrops are great, but be mindful of slippage. This time I directly jumped in with 800U, and bought and sold immediately for 770U. The slippage here is really hard to describe; the one-minute chart keeps spiking up and down. The airdrop might not have slippage yet, as it has high intrinsic value.
