Excepting the movies already mentioned here, I would also like to mention 3 Bitcoin documentaries which are very interesting:
First one talks also about Silk Road saga. Third one is first Bitcoin documentary made in Asia and many iconic figures appear in the film, such as Jihan Wu or executives of ViaBTC or other Asian crypto exchanges. Perhaps the most fascinating character from this documentary is a trader, whose face and voice are obscured, which brings more mystery to the movie. Among others, this trader also explain how he made his "
first barrel of gold".
