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

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

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.

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.

quantum is not why the whale sold

novo didn’t connect the two. he said it was one reason ppl are claiming for btc weakness, but he disagrees with that (this is clear if you read the full transcript)

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.

Reports note that such measures reflect planning, not panic. They show that developers and stakeholders are discussing options and preparing possible upgrades. That planning is part of normal risk management in a system that values longevity.

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.

The denial from Galaxy makes the quantum angle look like a post-hoc story that filled a gap in an already jittery market.
