Tyler and Cameron Winklevoss, the billionaire founders of the cryptocurrency exchange Gemini, have each contributed $1 million in bitcoin to support Donald Trump’s presidential campaign. The Winklevoss brothers, whose company recently settled with US and New York state financial regulators over allegations of misconduct, announced their donations on the social media platform X, without specifying the recipient of the funds. The crypto industry is increasingly trying to influence US politicians as it faces heightened scrutiny from regulators.
