I've had my money stolen from Poloniex. Contacted poloniex- they said they can't do anything.
At this point I know there's no way to get it back, but I just want to report it somewhere within the legal system.
Can I report it to FBI or the local Police?
Any other places/people to report to?
That is something you cannot do anything about even if you get to trace it and then taint the coin there is not much thing that can do because of the fact that there are several mixing services on the web that can neutralize that. This is one disadvantage we have to live with. I have fallen victim before that eventually I had to let go. But I still blame poloniex for not accepting responsibility which is something they really should be called out for.
