Binance occasionally hosts crypto airdrops, where users can receive free tokens by holding a certain amount of specific cryptocurrencies in their Binance wallets. Airdrops are typically announced on Binance's official channels and require users to complete specific tasks to qualify for the tokens. Participation in crypto airdrops can provide opportunities to explore new projects and potentially earn rewards without making additional investments. Users should exercise caution and verify airdrop announcements to avoid falling victim to scams.
