I have already started experiencing the OKX product: one ️⃣ The "knock out" mechanism of FCN: Before the dual currency, only a low buy price or high sell price of USDT could be set, commonly known as the strike price. If that price is not reached, the designated return will be obtained upon maturity. But FCN has added a knock out price, which means you can set a reverse price, and if it is touched, the knock out will be executed directly at the current week's price. For example, if USDT is set to buy Bitcoin at a low price of 65000, but the strike price is set at 83000 over a period of five weeks, then if the price reaches 83000 in the second week, the strike can be made that week and the previous profits can also be obtained. Equivalent to meeting the requirements of both high annualization and avoiding the risk of currency exchange at maturity. two ️⃣ Satisfy the price range that the dual currency has not yet met. Because dual currency is essentially a fixed option packaged as a wealth management product, there are some price ranges that we need to set that dual currency cannot achieve, but FCN can set prices to meet more needs.
