Quantum Computing Could Kill Bitcoin 🧠 Shor’s Algorithm Threat Quantum machines running Shor’s algorithm can derive your private key from its public key—breaking Bitcoin’s ECDSA signatures in minutes once the hardware is powerful enough. 🔢 Qubit Requirements Estimates suggest you’d need on the order of 2,800 perfect logical qubits (millions of physical qubits after error‑correction) to crack a single Bitcoin key—today’s quantum computers have only a few hundred qubits at best ⏳ Timeline Expert
