Quantum computers could bring lost Bitcoin back to life: Here’s how

Quantum technology, rooted in quantum mechanics, has the potential to revolutionize data processing and problem-solving, currently being 300,000 times faster than traditional computers. This advancement poses risks to Bitcoin's cryptographic underpinnings, specifically targeting the ECDSA that secures wallets. Quantum computing could allow malicious entities to derive private keys from public keys using Shor's algorithm, which may jeopardize Bitcoin holders, especially those linked to older or reused addresses. Estimates suggest 2.3 to 3.7 million Bitcoin are permanently lost, which could resurface if quantum computers crack their wallets. Ethical concerns also arise regarding the potential reintroduction of lost coins into circulation, which could disrupt Bitcoin's scarcity and market value. To mitigate these risks, users should avoid address reuse and utilize wallets that support newer protocols. Ongoing research into quantum-resistant wallets indicates that Bitcoin is not under immediate threat but requires vigilance.
