OKX's USDG looping to earn coins, The money you put in first borrows USDT, which is then used to subscribe to PT-USDG and YT-USDG. PT is deposited into Aave as collateral to support the next round of borrowing, while the underlying yield of USDG is retained in your wallet as YT. The more loops you do, the larger your YT holdings and overall lending/borrowing positions grow, amplifying both your returns and bonuses. So the structure is: using USDT debt to leverage and increase your exposure to USDG's underlying yield. How much you earn depends on how much yield USDG generates during this period and how high the cost of borrowing USDT is. Looping is not risk-free. If borrowing costs exceed asset yields, net returns can turn negative, and you could lose your principal. You can initiate redemption at any time, but if the health factor is too low, protocol liquidity is insufficient, or slippage exceeds the limit, it may fail or be delayed. In such cases, you'll need to reduce the number of loops or add more collateral before retrying.
