Comparison of Leverage and Borrowing Costs

Some were used in the YB Prime Sale, calculating the BNB price based on the repayment amount (1350)

Using 9000u full warehouse leverage to borrow 3.01 BNB,

Repayment after the event ends is 3.0109975;

Withdrawal fee: 0.012u

The actual leverage cost is: 1.3386u

Compared to a friend's loan from AAVE,

Also borrowing 3 BNB,

The interest is only: 0.0000047

Just 0.006u !!

The fee difference is a bit too much, so I checked the interest rates,

Leverage annualized at 76%,

aave annualized at 3.46%

The high annualized rate during the BNB event can be understood,

but I don't quite understand,

With an existing contract, what is the point of coming back for another leveraged transformation??
