After discovering that OKX supports USDG as collateral recently, stablecoin players have added another gameplay option. If you are interested, you can take a look. Placing USDG in the account itself generates profits, but using it as collateral to borrow USDT yields lower interest rates. Mortgage USDG → borrow USDT → exchange for USDG and deposit it to continue earning. Because they are all stablecoins that circulate between each other, unlike playing contracts where you keep an eye on the market every day. The main profit is the intermediate spread. After a few cycles, the annualization will be much higher than simply depositing coins. However, the essence of this thing is still revolving loans, and the returns are quite good. It is still necessary to pay attention to controlling the position and safety margin.
