Huobi HTX has launched CVXSTOCK/USDT and TLT/USDT perpetual contracts, allowing users to take long or short positions with 1-20x leverage. From Sept. 18 through Sept. 22 at 15:00 UTC+8, registered users who trade the event contracts and meet specified thresholds can compete for a share of a 1 billion HTX token prize pool. Perpetual contracts are derivatives that do not have a fixed expiry date.
