i also lost 640000 batcoins

Hello.
I have really bad news for you - our base, as i see, was partly compromised and leaked to unknown hacker. Today i received a message from him, and threat that all our money will be withdrawn if we wouldn't pay him 10 BTC. Even though we stored user passwords as hashes, some of them was decrypted and used to steal people's money. We temporarily closed (or closed forever?) to think what we can do to refund our customers money, at least partially. We have lost ~40% of LTC, LEAF and part of NYANcoin amount. Sometimes i like the idea when no other exchange accept any money we trade...
Thank you, hacker. You just killed one of the part of cryptoworld bright future.
