I have a question about TUSD. Because I saw that some other exchange list TUSD and they are having this kind of promotion. 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. 22, 22:00, 2018 (UTC+8). So I'm thinking when will Binance have this too?
