France Targets Crypto Wallets Over €100K With Proposed €10,000 Fines for Non-Disclosure - Bitcoin Foundation

France is considering a measure that would require holders of cryptocurrency wallets valued above €100,000 to disclose them, with non-disclosure potentially carrying a €10,000 fine. According to the Bitcoin Foundation, the proposal targets wallet holdings rather than transactions, placing the reporting obligation on the asset itself.

The development fits a broader pattern of regulators seeking visibility into crypto wealth. Unlike exchange-level reporting, which captures activity on centralized platforms, a wallet-based disclosure rule would reach self-custodied assets that currently sit outside conventional reporting channels. That distinction matters for investors who hold keys directly rather than through a custodian.

For markets, the immediate relevance is less about the fine amount than about precedent. If adopted, the framework could shape how other jurisdictions approach self-custody reporting and may influence compliance expectations for holders above the threshold. What to watch: whether the proposal advances into law, how the €100,000 valuation is measured and at what point in time, and what disclosure mechanics authorities specify.
