Apparently, it seems that Tillkoeln (the owner of Unnamed Exchange) has allowed the domain to expire. If you go to the website you are directed to a "domain for sale" page.
Has there been any update with regards to anything at all related to unnamed.exchange or the scammer (Tillkoeln) that operated it? I wonder how many victims there would have been and if any of them managed to take legal action to get their funds back.
I filed a police report and, as far as I know, the investigation is still ongoing.
