As far as I know, the BTC-e servers are in russia, US can't have taken them and so I don't think they have any private keys at all (maybe only Alexanders one from his phone).
So could it be this ETH move is done by the BTC-e admins for their new website???
From my understanding, from reading the indictment, BTC-E did have servers in United States.
Yes, but the question is, what are they defining as servers? I've heard their Metatrader servers were in the US ... they used Cloudflare for DDOS protection but clearly that has nothing to do with their servers. And whatever servers may have been seized (in US or EU) may have just been running scripts to remote servers. So the authorities may not have recovered anything valuable. This might explain the lack of announcement regarding seizure of funds.
