Btce was the most reliable exchange.
Define reliable. It was an exchange run in an unregulated grayzone with no oversight, by completely anonymous people who may have turned out to be money launderers.
If you truly want a safe & reliable exchange, pick one that is regulated and overseen by someone. Or one that makes their ownership and management public.
As it is, one of two things is the case:
1. The FBI has the cryptocurrency, in which case it is evidence in a criminal investigation and unlikely to be released before a conclusion of that investigation and trial. No one knows what happens after all that concludes - the FBI generally will auction off criminal money, but not necessarily legitimate assets.
2. The FBI does not have the crypto, in which case what happens to it depends on whomever is left at BTC-E - people who we still have no idea who they are, where they are, or what their intentions are.
It's a still a trust-based game. Hopefully it works out for everyone, but it is essentially crapshoot at this point.
