[Analysis: Quantum Computing Threatens Bitcoin Security, Experts Divided on Risks to 7 Million BTC] With the development of quantum computing technology, approximately 7 million bitcoins (valued at around $440 billion), including Satoshi Nakamoto's 1 million BTC, may face risks due to encryption being compromised. Zeynep Koruturk, a partner at Firgun Ventures, stated that recent research indicates the time required to crack RSA-2048 could be shortened to 2-3 years, potentially accelerating threats to elliptic curve encryption. Tether CEO Paolo Ardoino believes that reintroducing vulnerable old coins into circulation is better than changing consensus rules; Digital Citizen Fund CEO Roya Mahboob emphasized that freezing old addresses would undermine Bitcoin's immutability, and supporters should upgrade encryption technology to address the threat. Meanwhile, Jameson Lopp suggested migrating vulnerable tokens to quantum-resistant addresses through a soft fork to prevent wealth redistribution by quantum attackers. OP_NET co-founder Frederic Fosco argued that the quantum threat is an engineering problem that can be resolved through technological upgrades and should not be overly feared.
