There is no fixed time for the withdrawal of 360 IOUs. As long as the user meets certain withdrawal conditions, the system will automatically withdraw the amount for the user.
360 IOUs are comprehensively evaluated according to the user's borrowing and repayment on the platform. If the repayment behavior is good within a period of time, the amount may be increased. Therefore, if you want to increase the amount of 360 IOUs, you'd better repay them on time when using the loan, and don't be overdue. Once it is overdue, it will be more difficult to raise the amount.
