Jack Dorsey made headlines at the Super Bowl by wearing a T-shirt that paid homage to the iconic Nirvana smiley-face logo. The shirt had “Satoshi” written on it, referencing the mysterious inventor of bitcoin. This was quite noticeable, given that he was sitting in the stands with Beyoncé and Jay-Z.
Dorsey’s support for bitcoin is well-known, and he has been an outspoken advocate for the cryptocurrency. Along with Jay-Z, he launched Bitcoin Academy to provide a free, 12-week educational course on bitcoin for residents of a public housing complex in Brooklyn.
Dorsey and Jay-Z have been seen together in various places and have collaborated on business ventures, such as Square’s acquisition of Tidal. If you are interested in getting a shirt like Jack Dorsey’s, they were available on Etsy at the time of writing, though they were already in high demand.
