11 years ago today, on Halloween 2008, Satoshi shared the bitcoin whitepaper for the first time. The question is: why choose that date? Satoshi was extremely intentional, so it seems unlikely to be random. In this, we explore multiple explanations, including historical analogy to the Protestant Reformation as well as symbolic connection to Samhain/All Saints Day. Ultimately, we conclude that what matters is the fact that the myth-making enabled by Satoshi's departure from the scene is one of the most remarkable and unique attributes of bitcoin.
