You earn ETH staking for helping secure the network. When you stake on Gemini Staking, we create validators on the Ethereum network and receive rewards for performing various operations as intended by the protocol. The staking rewards depend on the total amount of ETH staked on the Beacon Chain and the yield amount the network is offering. When there is a small amount of ETH staked, the protocol rewards will be larger to incentivize more people to stake. When the amount of staked ETH increases, the reward goes down.
