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.
This seem to be a tactical move from binance because hundreds and thousands of users were using trc20 usdt since erc20 usdt transactions were expensive, now they have applied fee for trc20 usdt so that everyone would get attracted to busd but personally i think 0.20 usdt fee is cheap and will not change my choice for sure.
