Airdrops in digital exchanges are promotional events where cryptocurrency projects distribute free tokens to users to boost engagement, reward early adopters, and increase market visibility. Recent examples include Binance’s airdrops for tokens like ZORA (4,276 tokens to eligible Alpha users, April 23, 2025), SIGN (1,500 tokens, April 28), and Hyperlane (HYPER), targeting BNB holders. MEXC’s report notes airdrops drive up to 35% of new user registrations, particularly in regions with limited banking access. The MilkyWay airdrop (MILK) and Cardano’s Midnight (NIGHT) airdrop for 37 million users, including XRP holders, are also notable. While airdrops enhance user acquisition and community building, they can introduce price volatility, as seen with ZORA’s anticipated $0.02-$0.03 launch price. Eligibility often requires holding specific tokens, trading history, or wallet registration, with exchanges like Binance, Bybit, and MEXC leading listings.
