BlockBeats reported this morning that documentary producer Cullen Hoback and HBO recently announced the upcoming documentary film (MoneyElectric: The Mystery of Bitcoin), which attempts to decipher the identity of Satoshi Nakamoto. (MoneyElectric: The Mystery of Bitcoin) will be broadcast on HBO on October 8. The film interviews people who claim to have been in close contact with the founder after the release of Bitcoin. It indicates that Satoshi Nakamoto may not be one person, but a group of people. However, the trailer does not provide enough information to reveal the identity of Satoshi Nakamoto. Rumors that Satoshi Nakamoto's identity has been exposed may just be hype for the movie.
