$9 Billion Bitcoin Dump Sparks Talk, But Galaxy Digital Dismisses Quantum Link

Trusted Editorial content, reviewed by leading industry experts and seasoned editors. Ad Disclosure Galaxy Digital moved quickly to push back on a narrative that a massive Bitcoin trade it handled was driven by fears about quantum computers.

Reports say the massive trade happened, but the firm’s researchers made it clear that the motive was not a sudden technological panic.

According to Alex Thorn, Galaxy’s head of research, the trade—executed on behalf of a wealthy client—was not about Bitcoin’s resistance to future quantum attacks.

The firm released its quarterly figures at the same time, showing a net loss of $482 million in the fourth quarter of 2025 and a $241 million loss for 2025 overall.

Those numbers, paired with the large trade, fed a rumor that rippled through crypto channels and social feeds.

Market Timing And Headlines

Bitcoin briefly slipped below $75,000 around the same time, and that price move magnified chatter. Some people connected the whale sell-off to an emerging tech threat.

Reports say a handful of market commentators pointed to quantum computing as the reason for the sell. But many experts pushed back, arguing that the timeline for a quantum machine capable of breaking Bitcoin’s cryptography is long.

Adam Back, a long-standing voice in the space, has argued that a meaningful quantum threat is decades away, not a near-term event.

Vitalik Buterin, Ethereum co-founder, agreed that blockchains could adopt stronger signatures well before any widespread risk materializes.

Andreas Antonopoulos, a well-known Bitcoin educator and author, has emphasized that if quantum computers ever became that powerful, many global systems would already be affected, not only crypto.

BIP-360 And The Community Response

A defensive step has emerged inside the ecosystem: supporters and some fund managers have been promoting BIP-360, a proposal that would add a post-quantum signature option for vulnerable Bitcoin addresses.

Trading Reasons Can Be Mixed

Large holders sell for many motives: tax planning, portfolio rebalancing, liquidity needs, or strategic hedging. It is rare for a single rationale—especially a speculative technology fear—to explain a trade of this size without other corroborating signals.
