Mt. Gox, the Tokyo-based Bitcoin exchange that halted withdrawals this month, went offline as a document surfaced alleging long-term theft of about $365 million in the digital currency.

A document posted online that appeared to be an internal strategy paper said unidentified thieves stole 744,408 Bitcoins from the exchange -- about $365 million at current rates -- and that the theft “went unnoticed for several years.”
