It seems there is a % based on the tier. I remember it only shows the highest % for the first 500 USDT. If you send more, the % will decrease.

Brothers, can I ask about the very high interest rates for USDT and USDC that are currently staking? How is this possible? The flexible interest rate is up to 17%-19% per year.
So now if I borrow money from outside to deposit it here for savings, that would be great, right?
