Moreover, if someone wants to find more easier way, then they can use  centralized exchanger, from this point of view, I will put Kucoin first because here you can exchange your coins only by mobile verification- https://www.kucoin.com/trade/BAT-USDT.
There is one more option which is MEXC exchanger it can also use for that- https://www.mexc.com/exchange/BAT_USDT.
