$ETH I understand now! You mean the profit from lending interest and not the profit from price movement in the market.

On the Binance platform, you can borrow money from the platform to execute trading deals or even lend your money to others to earn interest (financing) for that lending. The profit you are talking about is the return from lending, not the return from market movement.

What is lending interest?

Lending interest is the return you receive for lending your coins to other traders or the platform itself, in exchange for daily, weekly, or monthly interest.

Typically, this interest is predetermined and varies depending on the currency you lend.
