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.
yes right - the case is now in the hands of the police. I trust in them that they use the international investigation methods that they have. Due to the amount of money it is likely that they really follow the traces. Let's see what they can do.
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.
I put the addresses into the public because many different coins are stolen and I do not have the capacity to trace all of them. I am quite sure the hackers do not use them in a way that it can be traced easily.
Based on the amount of outputs, I wouldn't be surprised if they mixed them to be completely honest.
That's a hard road to follow, I'd say your best piece of information at this point would be the attempted Gmail access by far (ie: the ip address you have)
