It's nice to see a project that was presented to the community/tested by the community some years ago has finally reached the moment of coming out live!
You surely took your time, but, on the other hand, launching an exchange in the bull run should have its benefits in attracting customers (traders).
I've been one of the "testers" back then, I remember the exchange had an overly simplistic UI, but it was functioning well. I see now why. No KYK + Tor is a very good combo.
However, after logging in I've found pretty much same old UI which, although I understand why is so bare, still needs the touch of a designer imho (for example others' orders and the liquidity should be visible, for example the bottom buy/sell is too easy to miss)
I think I've also told you back then that, although the collaboration was good, you seem to be more a software developer than a people person. This announcement also shows you are more a developer than anything else.
So, while I wish you a warm welcome back and best of luck with your new exchange, I will also recommend you consider a collaboration with [1] somebody who has seen many more exchanges and has designer skills and [2] a peoples person to do PR and advertisement on the forum and other places too. Possibly with some liquidity providers too, at least at this early stage.
Imho we are in the days when an image or gradient color and better positioned table can draw more customers.
Again, good luck!
