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.
I'm pretty sure that if you exchanged at CoinWale you're giving the owner of CoinWale referral commissions.
Which is completely alright. Good on you sir, and hope you continue doing honest business
