Token airdrop: A crypto platform, such as a decentralized exchange (DEX), decides to create a native token. To reward its current user base, the project sends half of the total token supply to users’ wallets based on the volume each user has traded on the platform.

NFT airdrop: An NFT project might wish to generate interest in their current NFT sale by promising holders of that NFT that they will be airdropped a future NFT. This causes their current NFT sale to sell out, and keeps the community engaged with anticipation for the next NFT drop.
