Tron founder Justin Sun has sued Bloomberg in Delaware, USA, alleging that it plans to disclose the detailed types and quantities of his cryptocurrency assets in the 'Billionaires Index' and related reports, violating a previous commitment to 'only show the total amount and maintain strict confidentiality,' which could pose security risks such as hacking and personal attacks. Sun is requesting the court to issue an injunction to prevent the disclosure and seeks compensation for legal fees. (cryptonews)
