The DeFi protocol distributes tokens to their users, and has sparked a frenzy of "liquid mining". Take the most famous liquid mining project as an example: Compound Finance. They send the protocol token to their depositors and borrowers. Compound Finance said that this is for more decentralized governance, and they hope to empower people who frequently use the protocol.
Recently, many DeFi projects have introduced tokens in their systems. Whether it is governance/protocol/ownership/any token, each token is used for voting or fee sharing, or both.
