Crypto in your own wallet? France wants to take a closer look from 100,000 euros

France plans to introduce a reporting obligation for self-custodied crypto holdings above €100,000, according to BTC-ECHO, targeting wallets that currently sit outside the reporting perimeter of centralized exchanges. The move would require investors holding bitcoin (BTC) and other tokens in non-custodial wallets to declare those assets to authorities, with potential costs for non-compliance. The proposal reflects a broader European push to close data gaps on self-custody as the Markets in Crypto-Assets (MiCA) framework takes effect. It matters because a large share of crypto holdings sit in private wallets that regulators cannot currently see, and the €100,000 threshold would capture a significant slice of retail and high-net-worth investors. What to watch next is how the reporting duty is enforced, whether it aligns with MiCA and DAC8 tax-reporting rules, and whether other EU member states follow France's lead.
