When the hodl bonus is accumulated for 84hr/168hr, and if you deposit 100 SING once more, the hodl bonus is updated and a boost of 15%, which is half of 30%, is given. So if you are currently staking 200 SINGs, hodl bonus of X1.15 is applied and you will earn USDC with 230 points. If at this time, the total of everyone's points is 1200 points, you will get 20000$X(230/1200)=3833$ per day.
