There are two potential reasons for this:

  1. The minimum amount for withdrawal is 10 USDT (equivalent in BTC), check that you have mined at least this amount.
  2. The mining process is still active. Withdrawals are not possible while the mining process is still ongoing. Wait until mining has finished and then withdraw.
Your earnings will be exchanged for USDT and credited to your USDT Bonus wallet within 72 hours.
