If you can't guarantee that a margin deposit won't collapse, why are you asking users to make margin deposits in the first place, especially with high interest rates? And then you can't guarantee compensation if something goes wrong. Some might say, "You don't have to use it." Please, you're Binance. If I issue an altcoin and offer you a 100% annualized return, would Binance allow me to use it as high-value over-collateral? Since Binance has already allowed USD1 as high-value collateral, you have to guarantee its security. @binancezh Otherwise, just delist USD1.
