this is just my opinion
The mixer charges very high fees. I wonder if bitfinex 120k btc hacker sell btc by mixers or not. They may already sell the hacked coins. Any address of that 120k addy?
Bitfinex keeps dead silence about this address pretending that it will help investigators catch the thief (provided there was one in the first place). Whether it will actually help them do this remains to be seen, though. So far the hack looks more like a deliberate scam or an inside job...
In any case, Bitfinex seems to be doomed already
Yes, it is over for bitfinex. People should avoid to trade there, they must be next mtgox.
