All these days, it was free or zero cost to withdraw USDT TRC20 but suddenly from today, they have changed it to 0.20 USDT. I don't know if BUSD fee was 0 from the beginning or not but now it has been decreased to 0. The target is to boost the use of BUSD. This is the manipulation of Binance. There’s more to come.
What a coincidence, I actually ran into something similar with another exchange called whitebit.
Though on the higher side of fees two days ago I actually noticed these guys had started including withdraw fees of 0.5 usdt trc20 from being free of charge so am now left to wonder if these exchanges have some sort of conscience to charge or one of exchanges got the idea from the other....or promoting one coin over the other ....
