# Halving ENG

**Bitcoin Aid** adopts a contribution system based on a halving model, inspired by Bitcoin's progressive reward reduction mechanism. As the project progresses, the rewards for contributors are reduced according to the stage of the contribution pool. This model promotes scarcity and increases the value of the tokens over time.
