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?
No there are no ways to get back coins even the poloniex its self, there are no legal system to fix this problem
because actually there are no rules on bitcoins include the risk losing bitcoins,
bitcoins is not stocks, gold or currency that there are rule for them, bitcoins is digital goods on the internet
so the risk losing digital coins must be taken by the user's coins.
