An ancient Bitcoin whale, dormant for 14 years, recently transferred 80,000 BTC—valued at approximately $8.6 billion—across eight wallets, each moving 10,000 BTC to new SegWit addresses (from legacy “1-” to modern “bc1q-” formats). This event, reported on July 4, 2025, sparked speculation about the motive, with some suspecting a hack due to a prior Bitcoin Cash (BCH) test transaction noted by Coinbase’s Conor Grogan, suggesting possible private key compromise.
However, Arkham Intelligence, supported by multiple sources, indicates no evidence of selling or mixer use, suggesting the transfers were likely for a wallet security upgrade to enhance efficiency and reduce fees. The funds, originally mined in 2011 when Bitcoin traded between $0.78 and $3.37, remain untouched in the new wallets, and Bitcoin’s price showed minimal disruption, dipping 2% from $110,000 to $107,600.
Additionally, Ledger CTO Charles Guillemet noted that OP_RETURN messages claiming legal possession were sent to the wallets before the transfers, possibly prompting the owner to move funds preemptively. Speculation about the whale’s identity includes early Bitcoin investor Roger Ver, though this remains unconfirmed. The transfer’s scale, representing a 13 million percent return on the initial investment, underscores its significance, but no immediate market impact suggests a technical move rather than a sell-off.

Bitcoin also hit an all-time high weekly close, trading above $108,000, with some sources citing $110,000 as a recent peak. This resilience indicates strong market confidence despite the whale’s activity. The transfer of $8.6 billion in BTC did not cause significant price volatility, with Bitcoin trading steadily at $108,000–$109,000, slightly below its all-time high weekly close of $111,814. This suggests strong market absorption, likely due to institutional demand (e.g., 131,000 BTC held by public companies and 111,000 BTC in ETF inflows in Q2 2025).
If the whale decides to sell, the sheer volume (80,000 BTC) could flood the market, potentially triggering a sell-off. This is a concern given the trend of early holders selling into ETF-driven demand, as noted by 10x Research. However, no exchange transfers have occurred, reducing immediate fears. The possibility of a hack, raised by Coinbase’s Conor Grogan, highlights vulnerabilities in dormant wallets. A single Bitcoin Cash test transaction before the BTC movement could indicate private key compromise, though no evidence confirms this. If true, it would be the largest crypto theft ever, shaking trust in wallet security.
Ledger CTO Charles Guillemet noted OP_RETURN messages sent to multiple dormant wallets, including these, claiming legal possession. This could signal attempts to exploit inactive addresses, prompting owners to secure funds or upgrade addresses, as Arkham suggests. Arkham’s theory that the whale moved funds to SegWit “bc1q-” addresses for better security and lower fees reflects Bitcoin’s ongoing adoption of modern standards. This could encourage other dormant holders to upgrade, improving network efficiency but also increasing on-chain activity that might be mistaken for selling.
The movement of such a large sum from a 14-year-old wallet fuels speculation about early Bitcoin adopters (e.g., Roger Ver or early miners) and their intentions. It reinforces Bitcoin’s narrative as a store of value, with unrealized gains from $0.78–$3.37 per BTC in 2011 to $108,000 today, but also stokes fear of massive dumps by early holders. The OP_RETURN messages claiming legal possession raise questions about how dormant assets are treated under law. If linked to figures like Roger Ver, recently released from prison, regulatory scrutiny on early Bitcoin holders could intensify, especially if funds are moved to exchanges.
Arkham Intelligence and parts of the community believe this is a routine address upgrade. The shift to SegWit addresses aligns with Bitcoin’s technical evolution, reducing fees and improving security. No exchange transfers, stable market prices, and the use of modern “bc1q-” addresses support this view. The lack of selling pressure suggests the whale is securing, not liquidating, assets. This camp sees the event as bullish, showcasing Bitcoin’s resilience and the prudence of long-term holders adapting to modern standards.
Coinbase’s Conor Grogan and others wary of hacks point to the BCH test transaction and OP_RETURN messages as red flags. The timing, after years of dormancy, and the scale of the transfer fuel suspicions of foul play or a prelude to selling. The BCH transaction could indicate private key testing, and OP_RETURN messages targeting dormant wallets suggest external attempts to claim or provoke movement. Speculation about Roger Ver or other early adopters adds to fears of a potential dump. This camp views the event as a potential threat, either from a hack undermining security or a whale preparing to sell, which could crash prices given the 80,000 BTC’s market weight.
The lack of exchange activity and stable prices lean toward Arkham’s address upgrade theory, but the hack concerns can’t be dismissed without further transparency (e.g., confirmation from the wallet owner). The community’s split reflects broader tensions in crypto: optimism about Bitcoin’s growth versus fears of vulnerabilities and market manipulation.
