Im staking WSGB, EXFI, SFIN and SGB/CAND for SFIN rewards which I claim daily. You don’t have to claim them daily but I do because once I claim them I add them to the staking pool where Im staking SFIN so I can earn more SFIN.
If you don’t claim them the rewards will keep building but might as well claim them and put them to work in the SFIN liquidity pool where u can earn more SFIN.
