According to @Andre_Dragosch, Bitcoin’s network security is not the near-term weak point; the main quantum risk is to legacy wallets with exposed public keys that could be derived via Shor’s algorithm once sufficiently powerful hardware exists, not via brute-force of private keys, which is infeasible today, source: @Andre_Dragosch on X. For context, Google’s Willow system has 105 physical qubits, while breaking Bitcoin’s ECC would likely require roughly 5,000–10,000 logical qubits, implying hundreds of thousands to millions of physical qubits, placing the threat multiple engineering breakthroughs away, source: @Andre_Dragosch on X. Bitcoin’s network currently runs at about 1 zettahash per second, vastly beyond the reach of current quantum machines and expected capabilities in the foreseeable future, reinforcing low network-level risk for traders, source: @Andre_Dragosch on X. The concentrated exposure lies in older addresses: estimates suggest 4.5M+ BTC sit in dormant wallets that may never upgrade to quantum-resistant signatures, and a forced migration or sudden movement of these coins could create material sell pressure, source: @Andre_Dragosch on X. Timeline opinions vary widely, with ranges cited as 2029, around a 20% chance by 2030, and 2045–2065, highlighting uncertainty but also time for Bitcoin to implement quantum-safe BIPs and coordinate upgrades, source: @Andre_Dragosch on X citing @caprioleio, @VitalikButerin, and @adam3us. For trading strategy, the takeaway is low near-term quantum risk to BTC’s consensus while monitoring on-chain activity of Satoshi-era and other legacy wallets for unusual spending that could signal supply overhang, plus tracking progress on quantum-resistant BIPs as a mitigating catalyst, source: @Andre_Dragosch on X. Traditional finance may face quantum risk earlier due to widespread RSA/ECC usage in authentication and interbank communications, which, if compromised, could shift relative risk perceptions and support BTC’s digital bearer asset narrative, source: @Andre_Dragosch on X.
