Former U.S. President Donald Trump has made history as the first known ex-president to make a purchase using bitcoin, according to a report by Fox Business. Trump was at PubKey, a cryptocurrency-themed bar in New York City, when he ordered a burger and used bitcoin to pay for it with the assistance of an aide. This event, as described by Fox Business, marks "the first known time a former U.S. president has publicly used the bitcoin network." The integration of cryptocurrency into the mainstream financial system continues to gain traction with Trump's recent bitcoin purchase. As the digital asset landscape evolves, it remains to be seen how other public figures and institutions will embrace cryptocurrency in the future.
