I do not understand about tradebytrade. Why
https://coinmarketcap.com/ shows the trading volume of xbc is 2.97 BTC ($ 19,373), but when I go to tradebytrade, there are no sell and buy orders. Who can explain to me where the volume of 2.97 BTC comes from?
I don't understand it either myself.The best option is to use their support/enquiries desk or send them an email or tweet and ask them about it.They would be best able to explain this I imagine.
