Mr. Shrem’s Twitter photo. In a scene out of a Scorsese film yet to come, self-described “Bitcoin evangelist” Charlie Shrem was arrested at John F. Kennedy International Airport on charges that he schemed to sell more than $1 million in Bitcoins to users of the Silk Road yesterday. Put this arrest right above Dogecoin and Coinye West on the list of reasons why Bitcoin is the Jonah Hill in The Wolf of Wall Street of currency: no matter how much they strive to be taken seriously, the Bitcoin community remains a punch line. Mr. Shrem, 24, is the CEO and compliance officer of BitInstant, a Bitcoin exchange company.
