I am sorry to say, however the money is more likely then not gone. Whoever stole your funds is most likely going to use some kind of mixer/tumbler which will mean that you will think you are tracing the funds but in reality someone completely unrelated to the attacker/thief is using/moving the funds. In theory you could use some kind of blockchain analysis tool/software to try to figure out which mixer the funds were sent to and when, however with dealing with that small of an amount it will be difficult to determine "where" the mixer sent the funds to (e.g. what were the "exit" addresses of the mixer)
1) Not my money, just to be clear, I was brought in at the time.
2) I deal with other cases which use tumblers. They're a pain but not impossible to track money through. The real problem is even when on the other side, what can you actually do to find out who people are and even then get the money from them? It's very difficult.
However, that shouldn't stop us trying (what you say is completely correct of course and my client has written the funds off, unhappily).
