Cryptocurrency airdrops are promotional activities used by blockchain projects to distribute free tokens to holders of specific cryptocurrencies. These giveaways aim to increase token circulation, attract new users, and boost community engagement. Participants typically qualify by holding a minimum amount of specified tokens in their wallets or by completing tasks such as joining social media channels, contributing to discussions, or referring friends. Airdrops can vary widely in value and frequency, from small-scale distributions to larger initiatives aimed at fostering adoption and liquidity. While some airdrops result in valuable tokens that can be traded or held for potential future gains, participants should exercise caution as not all airdrops may lead to significant returns or liquidity opportunities.
