Non-custodial Bitcoin exchange Bull Bitcoin announced on the 8th that it has submitted a request to the French Supreme Administrative Court (Conseil d'État) to revoke a French government decree implementing the European Union (EU)'s cryptocurrency tax reporting regulation, 'DAC8'. Bull Bitcoin argued that the regulation could pose surveillance and physical risks to up to 135 million European cryptocurrency holders. DAC8 is a system that mandates cryptocurrency service providers to collect users' identities and transaction data and automatically report them to national tax authorities, with the collected information being shared among EU member states. This directive came into effect on January 1, 2026. Through a press release, Bull Bitcoin pointed out that DAC8 risks creating a 'massive database' linking users' legal identities and residential addresses, including transactions unrelated to taxation. The exchange emphasized, "In a situation where daily data breaches and kidnappings targeting cryptocurrency holders are surging, building such a database threatens the physical safety of millions of holders and their families."
