Maybe you’ve seen his Bitcoin dollar bill on a billboard in Washington D.C. Or watched migrants tear down his mural of Venezuelan president Nicolás Maduro, in Cúcuta, a Columbian border town, as part of an agreed-upon protest. Or, perhaps, you raised an eyebrow at his Bitcoin stickers on a Bank of America ATM in San Francisco. Or knew someone that knew someone who took part in his auction for the least expensive art in the world, Black Swan, which sold for a millisatoshi. Cryptograffiti’s art is diverse, taking on many physical forms and media. But it’s guided by a singular purpose: educate others about the benefits of Bitcoin — a solution for a better world.
