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???
Servers are in USA at Equinix, at least some.
Btw to all....... chat channel about BTC-e at:
