The 500m_1001d_yield is lower than the 100m_1001d_yield because the 500m_1001d_yield is calculated using the Upi rewards system. The Upi rewards system is designed to reward users for their loyalty and activity on the platform. This system rewards users with a higher yield when they have been active on the platform for longer periods of time. Therefore, the 500m_1001d_yield is lower than the 100m_1001d_yield because the rewards system is rewarding users for their loyalty and activity over a longer period of time. The rewards system is designed to incentivize users to stay active and engaged in the platform, which is why the 500m_1001d_yield is lower than the 100m_1001d_yield.
