Jameson Lopp: Assessing Bitcoin Risks, Lessons from 200+ Attacks & Improving Security Posture.

A significant event in the cryptocurrency space unfolded on July 4, 2025, when eight Satoshi-era Bitcoin wallets—each containing 10,000 BTC—moved a total of 80,000 BTC after remaining dormant for 14 years. These wallets, dating back to the 2009–2011 era, were among the earliest to mine or transact Bitcoin. The transfers did not go directly to exchanges but instead were sent to new SegWit addresses, which are believed to be more secure against potential quantum computing threats due to their improved cryptographic properties [1].

The movement sparked immediate speculation regarding the underlying motives, with some suggesting a potential breach or the influence of quantum computing. This concern is rooted in the vulnerability of older P2PK and P2PKH addresses to quantum attacks, which could theoretically expose private keys. The 80,000 BTC moved originated from such addresses, which are part of an estimated 5.9 million BTC (about 25% of the supply) at risk from future quantum threats. By moving these funds to SegWit addresses, the wallet owner appears to be implementing a proactive security measure [1].

Further complicating the narrative, between July 14 and 15, 2025, an additional 28,600 BTC—valued at over $3 billion—was transferred to Galaxy Digital, with 9,000 BTC already sold. This activity coincided with a sharp decline in Bitcoin’s price, which fell about 5% from its recent all-time high of $123,000 [1].

The identity of the wallet owner remains a mystery, though analysis by Arkham suggests the wallets belong to a single entity. Speculation has centered around Roger Ver, also known as “Bitcoin Jesus,” who was released from bail in June 2025 just days before the transfers occurred. However, no definitive proof links Ver to the movement [1].

Adding to the intrigue, four OP_RETURN messages were embedded in the Bitcoin blockchain between July 1 and July 4, 2025. These messages included claims of legal possession of the wallet and an ultimatum requiring the wallet owner to prove ownership through a transaction by September 30, 2025. While these messages have not been confirmed as evidence of a hack, they have been interpreted as part of a potential spam campaign or legal stunt to pressure the wallet owner into revealing themselves [1].

Bitcoin developers are actively addressing quantum computing risks through proposals like the Bitcoin Improvement Proposal (BIP) led by Jameson Lopp of Casa. The proposal aims to phase out wallets vulnerable to quantum attacks, particularly targeting the 25% of the supply currently at risk. The 80,000 BTC movement represents a key case study in how holders are adapting to future threats by upgrading their storage solutions [1].
