They posted again saying that the trading fee promotion got extended. read this. Users will enjoy 99% off the trading fees on TUSD trading pairs (BTC/TUSD, ETH/TUSD and USDT/TUSD) from Oct. 15, 22:00 to Oct. 29, 22:00, 2018 (UTC+8) good thing they did that. I'm hoping that this exchange do this as well.
