The rate of withdrawal fee is dynamic and may fluctuate according to $SSP's "Membership Index". The higher the membership Index, the lower the withdrawal fee. Membership Index = the number of DAO NFT * 100/circulated number of $SSP. When the Membership Index is greater than 0.65, more than 65% of the circulating $SSP is pledged, and the rate of withdrawal fees reaches the lower limit, 15%. As the membership index decreases, the withdrawal rate gradually increases. When the membership Index is less than 0.1, only less than 10% of the circulating $DMS are pledged, and the rate of withdrawal fees reaches the upper limit, 65%. Define the membership index as x, the penalty rate is y, and the specific formula for the withdrawal fee rate is: When x≥0.65, y = 0.15 When x≤0.1, y = 0.65 When 0.65>x>0.1, y=0.740909-x * 0.909 The parameters of the withdrawal rate will be adjusted irregularly with the progress of the project, and the subsequent DAO will be determined by the community governance after the start of the DAO.
