I am glad to see this happening, new exchanges adding DUO, but when we are in those ethical things, please let me explain you something.

First of all, if you want to be a not-decentralized exchange, when there is one point of failure, you can not hide who is behind. You use Let's Encrypt SSL certificate, which is ok, but then you hide the name of person/company which registered the domain and of course there is no mention on the site. So, a guaranty for someone who wants to send their coins is basically 0%. I am not accusing you that you are a scammer or not, just that how I see it is seen so many times until now. I even know some people who did the same. Also, you are a user here from April 12, 2019.
0% transparency = 100% risk. Sorry, but it is like that. There must be someone responsible for that kind of tools, not-decentralized exchanges.
What happened with "A decentralized Data Sharing Platform, Hosting and Content Distribution Network through Masternode Network" how that becomes a centralized exchange?
Cheers, wish you luck in further development.
