Let's assume the site is legit (old btce domain, posted on the forum, on the twitter account, it has the complete database ecc).
Ok to be honest I missed that they even posted it on their Twitter.
To be totally honest (and be the devil's advocate)
I have been surprise from the very beginning that the FED did not seize BTCe twitter account...
I mean twitter is in US, the feds could simply ask for the password and having it delivered in a couple of minutes.
Therefore, two options:
-everything is in FEDs hands.
-BTCE is back.
