Your passive rewards are given at 0.5% of the principal amount of all active packages.
For example, if you have a 1000 HU package and a 50 HU rebuy, you will receive 0.5% of 1050 = 5.25 HU per day.
Each membership or rebuy gives you 3x of the principal sum in total pending rewards. For example, a 300 HU membership will entitle you to 900 HU in total rewards eligible. Once the 900 HU has been fully disbursed, the membership will be “completed” and will no longer give out any more rewards.
Even if you have been doing rebuys every single day, your daily passive rewards would still fluctuate if some of your memberships are completed.
For example, if you did a 50 HU rebuy today, and your 300 HU membership was completed on the same day, your passive rewards for the day would actually decrease (a gain of 0.25 HU versus a drop of 1.5 HU).
The status of your existing memberships can be easily verified by clicking on the ‘Purchased Package List’ located on the top-right corner of your homepage to check.
No, the system is not wrong.
No, it really does not matter that you did not do any withdrawals, that does not affect the rate that your memberships/rebuys release their rewards.
