The distribution of rewards for USDD and other markets is dependent on the market's specific reward policies. Generally, rewards are distributed on a weekly basis, with the exact timing of reward distribution varying from market to market. For example, rewards for the USDD market are distributed on a weekly basis on Mondays, while rewards for other markets may be distributed on different days of the week. Additionally, the amount of rewards distributed may also vary from market to market. Therefore, it is important to check the specific reward policies for each market in order to determine the exact timing and amount of rewards that will be distributed.
