Good news, everyone!
The hacker (a bit of a misnomer, as he has pointed out) returned 50 BTC, and I have just distributed it to affected users. Looks like the other 65 will be sent, too.

Once you get back all 115 BTC and you have distributed them to the affected account holders, the situation will hopefully be completely remedied. I understand that the withdrawn 7000 XCP have been mitigated by the 12 BTC you received from the developers.
The commission of 2.5% that you have levied to raise 115 btc should ideally go to the bugs and security bounties now. You should have had a volume of at least 200 BTC since you raised the commission so I am guessing approximately 10 btc raised so far. Will you please consider donating these to the bounty?
I thank the person returning all the coins back to you and I hope the devs are able to involve him as an external security auditor as originally intended by them before he went AWOL
12 BTC did not buy 6100 XCP. I'm going to take inventory of everything now and see what the situation is. The white hat actually explicitly waived his claim to the 12 BTC, but I still think he should have anything left over.
