Bull Bitcoin has launched a legal challenge against France’s implementation of the EU’s DAC8 crypto reporting rules, arguing that the law forces crypto firms to collect and share excessive amounts of customer data.
The company said it filed its case before France’s Conseil d’État, the country’s highest administrative court, after DAC8 took effect on January 1, 2026. The rules require crypto-asset service providers to collect customer and transaction data and report it to national tax authorities, which then exchange the information with other participating jurisdictions.
In Europe, DAC8 has turned “Know Your Customer” into “Kill Your Customer.”
Today, Bull Bitcoin is officially opening the first legal front against DAC8.

Bull Bitcoin argues that the system goes beyond tax reporting by creating a large database containing users’ identities, home addresses, and crypto activity. According to the company, such centralized data could become a target for hackers or criminal groups if breached.
Bull Bitcoin says DAC8 puts privacy at risk
The company said the previous system required customer information to be shared only when authorities made lawful requests or when suspicious transactions were detected. Under DAC8, reporting becomes automatic, regardless of whether wrongdoing is suspected.
Bull Bitcoin also linked its legal action to the recent rise in kidnappings and violent attacks against cryptocurrency holders in several countries. It argued that large databases containing financial information increase the risk of sensitive data falling into the wrong hands.
The company is asking to overturn the French decree implementing DAC8. It also said it is prepared to take the case to the Court of Justice of the European Union and France’s Constitutional Council if necessary.
Can privacy challenges slow crypto reporting rules?
Bull Bitcoin is not the first crypto company to push back against government reporting requirements.
Industry groups have challenged similar rules in the United States, including lawsuits over the Internal Revenue Service’s broker reporting requirements and earlier legal battles involving transaction reporting obligations.
These lawsuits, such as those filed in the U.S. District Court for the Northern District of Texas, argued that the rules violated the Fourth and Fifth Amendments and the Administrative Procedure Act. While courts have rarely overturned tax reporting laws entirely, these cases have sometimes forced regulators to clarify definitions or narrow how the rules are applied.
That history suggests Bull Bitcoin faces a difficult legal fight. Even so, the case could influence how European authorities balance tax enforcement with privacy and data protection. If the French court raises concerns about the scope of DAC8 reporting, it could help future discussions across the European Union without necessarily blocking the framework itself.
In another court case development, Thai authorities issued an arrest warrant for Chinese businessman Wang Yicheng, accusing him of playing a central role in an alleged illegal cryptocurrency mining network that reportedly consumed around $28 million worth of electricity without authorization.
