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.
Actually in binance only tbe free of withdrew is low. From 0$ to 0.2$, other exchange had a free of 0.3-0.7$ for trc withdrew also.And the price of BNB was increased after a long time.So you can make a transfer of USDT to BNB and hold their.When the price of BNB had increased, you can withdrew Bnb to usdt and make a profit from it.
