After the event ends, if you do not actively redeem, your USDT will be automatically redeemed to your account within 4 hours; your other assets will continue to be used to subscribe to Simple Earn products. Rewards are calculated on an hourly basis. A. After subscription confirmation, Simple Earn interest will begin accumulating from the next full hourly calculation period, calculated according to the applicable annualized lending rate. B. After subscription confirmation, token airdrop rewards will begin accumulating from the next full hourly calculation period. If you subscribe during the pre-subscription period, airdrop rewards will not be calculated before the official start time of the event. C.
