And that's why people shouldn't be throwing around the phrase "decentralised" as they please. The fact that the exchange had a founder, who ran, managed, and operated it, should immediately have made the use of DEX terminology erroneous. The only good thing I suppose was that funds were never centralised but imagine what else he shared with prosecutors (the story claims his fines were actually reduced because he cooperated)? IP addresses? Emails (I don't know if ED uses it)?
Course they had a case. And made it well.
i'm starting to like the distinction between "non-custodial" and "decentralized". fully decentralized trading is a long ways off. every DEX today depends on various forms of centralized administration.

i suppose they do have IP address logs, don't they? but weren't users pushing trade transactions to public ethereum nodes anyway? no emails or other account details on etherdelta.
