I don't understand, if ethereum transactions are confirmed, and this time eth has no hard fork, how can you retrieve the hacked fund? How did you freeze the fund? I am very curious
Well the hacked funds are on an address on Bittrex, Bittrex can prevent this address from outputing transactions I guess, like if your bank froze your bank account ... For the recovering part, either the hacker is found and they return the funds or either Bittrex has the ability to transfer Xaurs from that address once the authorities permit it. (Just my hypothesis.)
Well, it is a great example of XAUR and Bittrex are professional teams, although the hacker hacked huge amount of money, the team did the best to prevent damage.
