The annualized return for bnb holders is also 6%, with an additional 4% interest, equivalent to earning only a 2% interest spread

Done.
Just staked 156 BNB to borrow 100,000 USDC, and then participated in the recent Binance USDC financial staking activity, with an annualized yield of 12%, earning about 33 USDC in interest per day, not too bad!
In addition to the staking financial returns, there is also an activity to share 150,000 USDC, not sure how luck will be at that time, hoping to win!
