This is my first time to hear about nexget.io. You can add a black interface for your website or use an option to choose the color for the site because white is too shiny
As long as you can maintain your site and working hard to promote the site, I am sure your site will grow and have a chance to compete with the other exchanges. But as we are concern with our identity, I hope you do not ask for KYC to your members but you can ask KYC for the member who wants to withdraw more than 1 BTC at once. You can compare with Binance because Binance allows its members to withdraw 1 BTC.
I do not register as a member, but maybe I will try to register and see how it looks inside the dashboard.
