What is Move to Earn?

Apps that use the "Move-to-Earn" (M2E) model allow users to earn rewards in the form of cryptocurrency for participating in fitness and sports activities. This is similar to "Play-to-Earn" (P2E) apps, which reward users for their contribution and skill, but M2E apps require users to be physically active rather than sitting and playing games. M2E apps often incorporate features of decentralized finance (DeFi) to reward users and give them a stake in the game.
