Thumbs up for releasing the Tor version of the exchange. I just had a look at it. It's simple and that's fine. I am happy there is a button to turn off the animations because the site is easier on the eyes without it.
One thing that stands out, though, is that big grey box that appears on the top left and towards the middle of the page. The text in it says <MEDIA> and displays the onion address. I am not sure why it's there. Does it have a purpose? My Tor privacy settings are at the highest level. Maybe the box would look differently if they were set at low or normal.
