as I see tokocrypto is based on "Binance Broker Benefit System", the same User Interface as binance: https://www.tokocrypto.com/
I've tried to find the volume of this exchange but unfortunately there are no integrations on cmc and coingecko. But as you say, Binance has a good reason to promote them, the question is if 50 min USD is a fair price, its the thing to DYOR
