Jack Dorsey was seen at the Super Bowl wearing a T-shirt that paid homage to Nirvana’s iconic smiley-face logo, but with “Satoshi” written on it. This drew attention not only to the shirt, but also to his surroundings, where he was sitting in the stands with Beyoncé and Jay-Z.
The T-shirt was a symbol of Dorsey’s public support for bitcoin, which he has been vocal about for years. Along with Jay-Z, he even launched Bitcoin Academy to provide a free 12-week educational course on the cryptocurrency to residents of a public housing complex in Brooklyn.
Dorsey and Jay-Z have been spotted together in various places before this, and have worked together 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, although they were already in high demand.
