This is really awesome news but where did you get the information that they will launch the exchange before 2019?
It's in their roadmap, and they mentioned it on Telegram as well. So the exchange is coming soon, it's getting HOT !!

Ah.. just saw that roadmap according to RM they are planning to launch the exchange by Q4 of 2018. Hopefully, they won't delay it 'coz 2018 is about to end.
moreover exchange? Dent is now in Binance, Kucoin, Coinbene, will Bitrex be the next home?
or DENT has its own platform exchanger program?
Dent would have its own exchange that trading crypto against data, this would increase demand & liquidity for Dent as well as increasing people awareness about Dent .
