Former President Donald Trump made headlines by purchasing burgers with Bitcoin at PubKey, a Bitcoin-themed bar in New York City. This marked the first public Bitcoin transaction by a former U.S. president, signaling a significant shift in Trump's stance on cryptocurrency. Trump, who once criticized Bitcoin as a 'scam,' now promotes a crypto-friendly agenda as part of his presidential campaign, aiming to position the U.S. as the 'crypto capital of the world.' The event saw Bitcoin's price rise by 4.7%, although experts like Cathy Mulligan and David Gerard suggest that this fluctuation is typical for the volatile asset. Trump's visit was also tied to the launch of his new cryptocurrency venture, World Liberty Financial, which aims to offer borrowing and lending services for digital assets.
