# 04. Liquidity Pools & Staking

By adding liquidity to a network, users can increase their chances of receiving airdrops and potentially earn rewards. It’s advisable to focus on protocols without their own token, as this can increase your chances of receiving an airdrop. However, adding liquidity to any protocol can be beneficial in terms of receiving an airdrop on the main network.
