The documentary claims to reveal the true identity of the "father of Bitcoin" and the parties involved firmly deny it. On Tuesday (October 8th) local time, the American "Family Box Office" (HBO) channel screened a documentary film called "Money Electric: The Bitcoin Mystery" for the first time. In this 100 minute film, in order to delve deeper into the origin of Bitcoin and the identity of its creator, Satoshi Nakamoto, filmmaker Cullen Hoback interviewed several early figures involved in the Bitcoin field.
