Woo continues to tweet about Bitcoin’s long-term outlook, often pointing out macro trends that will shape the market, and has attracted significant attention from the crypto community.
Woo tweeted late yesterday:
However, Woo ended the tweet by saying gold moons without BTC, which continues his early stance that Bitcoin is reeling from Quantum D-day threats. According to Woo’s earlier tweets, the premier digital asset’s price was negatively affected as soon as the Quantum threat became real in 2025.
He believes that the “Q-Day” threats would require significant mitigation from the Bitcoin network, and even then, the reported 4 million BTC, widely considered lost, could re-enter circulation if the underlying encryption were compromised. These 4 million BTC, representing 8 years of enterprise accumulation, would have to be factored in any long-term valuation narrative of the premier cryptocurrency, Woo argued.
Woo described the Quantum threat as a cloud hanging over Bitcoin’s head and said it could cause further problems. According to estimates, the Q-Day might take more than 5-15 years to challenge BTC encryption, and that is a long time to trade with a threat hanging over your heads, Woo tweeted.



 CoinShares, Strategy Downplay Imminent Threats
While Woo continues to raise awareness about Q-Day, other analysts believe the threat has been blown out of proportion and that there is no imminent quantum doom facing Bitcoin or even a portion of its supply.
In the report titled Quantum Vulnerability in Bitcoin: A Manageable Risk, CoinShares argues that while the new threat is a foreseeable engineering challenge, the threat to the BTC ecosystem is not imminent and will take time. The most vulnerable coins include the early 1.6–1.7 million BTC with visible, on-chain public keys (around 8% of the supply). These BTC are distributed across tens of thousands of wallets, each holding varying amounts, so tracking down and unlocking these reserves can take forever. But CoinShares does admit that the challenge remains.
Strategy, one of the largest BTC-holding companies in the world, has also emphasized that there is no imminent threat to Bitcoin and has established a Bitcoin security program to coordinate with cybersecurity experts going forward.
