Coinbase's Quantum Advisory Council says Bitcoin and other crypto networks should start preparing for a post-quantum transition ahead of any practical quantum attack. The group estimates roughly 7 million BTC could be exposed due to visible public keys or address reuse, including about 1.7 million BTC held in legacy Pay-to-Public-Key addresses.

Chainalysis reported on June 11 that an international law enforcement effort dismantled AudiA6, a laundering service it links to ransomware actors and darknet activity. The firm said AudiA6 processed about 10,333 BTC since launching in 2021, historically valued at roughly $389 million, and allegedly relied on more than 6,000 KYC-verified mule accounts plus exchange infrastructure.
