Over the weekend, Ukraine's vice prime minister and Minister of Digital Transformation, Mykhailo Fedorov, publicly appealed to "all major crypto exchanges to block addresses of Russian users." Fedorov tweeted in English: "It's crucial to freeze not only the addresses linked to Russian and Belarusian politicians, but also to sabotage ordinary users."
A spokesperson for the popular U.S.-based exchange told Decrypt, "A unilateral and total ban would punish ordinary Russian citizens who are enduring historic currency destabilization as a result of their government’s aggression against a democratic neighbor."
