Bitcoin Sign Guy prefers to keep his identity a secret, though we do know he is a Connecticut native who works at an unnamed crypto hedge fund. His father was a Central Intelligence Agency brat raised in Caracas, and his grandfather was a commie hunting CIA agent. He is an anarcho-capitalist who believes that monetary policy is an oppressive "instrument of statecraft" and has converted over 99% of his net worth into cryptocurrency. On July 12th 2017, Bitcoin Sign Guy stood behind Janet Yellen as she testified at a congressional comittee hearing and held a yellow notepad that said "Buy Bitcoin". Bitcoin Sign Guy's work at a Washington, D.C. free market think tank studying Bitcoin led him to that fateful moment. Soon after, one of Bitcoin Sign Guy's friends, @CryptoEthan, tweeted out a picture of Bitcoin Sign Guy along with a Bitcoin address and within days Bitcoin Sign Guy received over 6 bitcoin in donations (that was when bitcoin was only $2,400). Not long after the stunt, Bitcoin Sign Guy snagged an internship at the Competitive Enterprise Institute.  
Bitcoin Sign Guy is selling 21 prints of the "Buy Bitcoin" sign for 1 bitcoin a piece at BuyBitcoin.art. 10% of the proceeds are being donated to the legal defense funds for Ross Ulbricht and Julian Assange. Additionally, one print was donated to benefit Coin Center, to be sold at their Gala on May 13th.
