STEEM APR on Binance Earn is around 37%. Why? 🤔

It's interesting 🧐 A few weeks ago, STEEM APR on Binance Earn was less than 5%. But recently, it has surged about 40%. What's the source of 40% APR?

Binance exchange supports STEEM margin trading. In order to do the margin trading, you need to use USDT(Thether) as an collateral. If you set your position, the system will impose hourly fee. The fee is used to reward for Binance Earn users. That's the mechanism of the margin trading.

Anyways, high APR of STEEM can attract investors and derivative traders. It seems Binance knows how to create an economy outside of blockchains well 🤔
