B&C Exchange is quite dead. There is only a hand full of people left on the forum discuss.nubits.com that keep discussing about Nushares and B&C Exchange.
The architect Jordan Lee is gone after he pulled off a massive scam with a Nushares buyback program. It turned out that there is no way to find out his identity since he or she perfectly planned and disguised any single step over the course of the last few years. But I have heard from a group of people that they are trying to hold some of the guys accountable that play a minor role in that scam or at least provided some help to support it. One of those stooges belonging to Jordan Lee calls himself "jooize" on the forum. To be honest, I think it will be difficult to successfully press charges against him, but who knows...
