A few days ago, USDT TRC20 withdrawal from Binance, Bithumb global and Kucoin was totally free. But now Bithumb global is taking 1 USDT fee, Binance is taking 0.20 USDT fee. USDT TRC20 withdrawal from Kucoin is still free. However, I think all these withdrawal fees are relatively low and tolerable to us. Because now almost all transactions cost more than $1.
I just trade some ETH for USDT on binance and the exchange charged me 1 USDT on Tron, it's no more 0.20 USDT like OP said, I think this is climbing for unknown reasons, on coinEX tron usdt is still more cheaper than binance exchange and I don't know why
