In any case you should all report to the police, this is big money and you do not have to reconcile that it's all over and money lost. Too bad that you did not use HW before, when it is obvious that you have it in possession.
By the way - the hacker group (I strongly assume it was an organized group) came from the same location which is mentioned here:

The company Cherry Servers replied to my email request on the case:
Despite the best intentions, I'm afraid we cannot help you in this situation. We do not reveal any information about services associated with our prior or current clients to third parties. As our company is registered in Lithuania, we are only accountable to local law enforcement agencies in Lithuania and can only reveal such information to them when obliged to do so by local law or when a Lithuanian court order is received.
So it's your best chance to do something to report you case directly to Lithuania police, in a way to get some good lawyer maybe. Lithuania is also member of EU, so if you are also from EU there may be some legal mechanisms through which you could also take legal action.
Lithuania is also member country of Interpol, maybe they can do something to help you track hackers.
I'm interested did you trying to track stolen coins on block expolorers? In some cases they can be tracked to exchanges, and in some cases they can freeze such coins if there is any doubt about corrupt actions.
