The cryptocurrency exchange BTC-e went down two days ago at around 4 AM GMT, releasing a status on twitter saying they are having issues with their data centres.

Rumours of BTC-e cold wallets being emptied and mixed are spreading on Reddit although no proof of a connection is available.
The news comes at a time when Bitmixer has suddenly shut down and a Russian man in Greece has been arrested on charges of money laundering the equivalent of $4 Billion in BTC since 2011. Recently, two sources close to the exchange told Reuters that the man arrested in Greece is a key person behind the BTC-e crypto-currency exchange.
