Reading this:
"This cast of characters came to a head again this morning when news broke that an individual, said to be a native Russian, was arrested in Greece on money laundering charges connected to the use of bitcoin.
"
Makes the authorities of any country pay more attention to the bitcoin... coincidence that Russian guy be arrested for money laundering and btc-e being in maintenance.
"Update2: at the moment we are working on the restoration of service. Approximate terms from 5 to 10 days. Thanks for your understanding #btce," the exchange’s account tweeted.
In the next days we will know more things
I don't think that they could restored anything. If it is, then probably it should be up by now. I guess that BTC-e will not go online I'm sorry to say. The owners have been arrested, how can they function then. And the coins is gone forever as well. The servers might as well be confiscated and the logs being look up for possible identify of the hackers. We will probably know everything once we get another update in the next coming days.
