Jack Mallers, CEO of Twenty One Capital, has criticized traditional card networks like Visa and Mastercard for imposing high fees on merchants, claiming Bitcoin offers a solution. Speaking at Bitcoin 2026, Mallers highlighted that merchants lose 3% to 5% of each sale to these networks, which is then returned to consumers as rewards. He argued that this system unfairly burdens businesses and that Bitcoin can free them from such financial constraints, allowing for a more equitable payment system.
