　　II. Calculation of staking rewards 1. The staking rewards will be WEMIX, LDN, DOTR tokens acquired by participating in OKX Unidentified Jumpstart Mining. The staking rewards are calculated in real-time and can be withdrawn at any time. 2. Hourly user rewards equate to the amount of personal OKB staked / the total amount of OKB staked newly released tokens per hour. For example: If the amount of a user's OKB staked is 100 and the total amount of OKB staked at that time is 100,000, with the amount of WEMIX released per hour being 10,000, then the user's hourly rewards equal 100 / 100,000 10,000, which equates to 10 WEMIX. 3. When the project confirms the time of the token on-chain transfer, OKX will release a new announcement concerning the times for depositing, withdrawing and trading token.
