Take MAYC as an example to calculate the change in return rate brought by different number of people participating in the pledge. This model uses 10,000 and 20,000 MAYC to all participate in the pledge and lock up to 150 million APE to calculate the ROI; MAYC can mine 3.68 per day coins, the 3-month return ROI is 15.8%. In the extreme case of unlocking in March next year, U-based losses may occur.
