Tesla founder Elon Musk says the car maker will no longer accept Bitcoin for purchases. In a statement he cited concerns about the "rapidly increasing use of fossil fuels for Bitcoin mining and transactions". We get reaction to the news from Olinga Ta'eed, who is an adviser to the Chinese government on digital currency, and director of the UK-based Centre for Citizenship, Enterprise and Governance.
