* Available to all Soei app users.
* Personal rewards are divided into 4 rankings Silver, Gold, Platinum, and Diamond with the distribution ratio for each ranking and the required STP per ranking period as follows:

<table><thead><tr><th width="162">Personal</th><th width="143">Silver</th><th width="146">Gold</th><th width="154">Platinum</th><th>Diamond</th></tr></thead><tbody><tr><td>k=100%</td><td>50%</td><td>25%</td><td>15%</td><td>10%</td></tr><tr><td>Need STP</td><td>100</td><td>500</td><td>800</td><td>1,000</td></tr></tbody></table>

Your rewards for each ranking period are calculated using the following formula:

* A: Your reward
* B: Your STP
* C: Total shared reward of Personal reward
* kn: is the percentage ratio in each tier
* Dn: Total STP in each tier.

*Example 1: In this ranking period, you earned 850 STP. The total Personal Reward for this ranking period is $1,000. The total STP points in each tier, Silver; Gold; Platinum; Diamond respectively, are: 8,000; 5,000; 3,000; 2,500.*

*Based on the example provided:*

*Your reward calculation would be:*

*A = 850 \* \[(1,000 \* 50%) / 8,000 + (1,000 \* 25%) / 5,000 + (1,000 \* 15%) / 3,000 + 0]*

*Let's break down the calculation step-by-step:*

1. *Calculate the proportion of the reward allocated to each tier based on STP:*
   * *Silver tier: (1,000 \* 50%) / 8,000 = 0.0625*
   * *Gold tier: (1,000 \* 25%) / 5,000 = 0.05*
   * *Platinum tier: (1,000 \* 15%) / 3,000 = 0.05*
   * *Diamond tier: 0 (since your STP is less than the required amount for Diamond)*
2. *Multiply each proportion by your STP:*
   * *Silver tier contribution: 850 \* 0.0625 = 53.125*
   * *Gold tier contribution: 850 \* 0.05 = 42.5*
   * *Platinum tier contribution: 850 \* 0.05 = 42.5*
   * *Diamond tier contribution: 850 \* 0 = 0*
3. *Sum up the contributions to get your total reward: A = 53.125 + 42.5 + 42.5 + 0 = 138.125*

*Therefore, based on the example provided, your reward from the Personal Reward would be **138.125 USDT**.*
