What is the difference between your exchage and Nexchange itself? Your website is basically a Nexchange clone but with a different color scheme (with same rates, same fee and same "real time rates");
You can even find a "Coinwale is Powered by Nexchange" text at the bottom of the page. So what's new?
No major difference, you can exchange from any of the platforms.
An in-detailed answer will be added to our FAQ soon.
