According to an official announcement from PANews on October 28th, Huobi HTX recently launched several USDD-related promotions. From now until 18:00 (UTC+8) on November 3rd, users who complete the promotion registration, open a USDD Yubibao account, and switch their U-margin contract account to joint margin mode will enjoy multiple benefits:

1. Registered users can enjoy up to 10% annualized returns on their USDD holdings in their U-margin futures accounts. 2. Registered users who use USDD as margin for their first futures trading, with a trading volume ≥ 100 USDT, will receive a $2 equivalent in $HTX rewards. 3. Registered users who use USDD as margin for futures trading will enjoy a 0% transaction fee, with transaction fees reimbursed in $HTX. It's worth noting that users can use Huobi HTX's instant swap feature to exchange USDT for USDD, with no fees charged.
