Navi has partnered with OKX to organize a promotion event for XBTC. XBTC can be easily withdrawn directly from OKX to SU. XBTC is a BTC derivative token that OKX focuses on promoting. At present, the interest rate is negative, which is equivalent to borrowing USDC and making money without paying interest. But this collateral is limited to xBTC only. If you have idle BTC in hand, you can borrow some money to improve the utilization rate of funds Those who like revolving loans can also come in and enjoy pure interest. It's been a long time since I last had the experience of borrowing money without paying interest and still earning interest.
