Bitfinex Says Current Quantum Computing Power Cannot Break Bitcoin, Sees Risk After 2030s

Bitfinex stated on Feb. 20, 2026 via X that existing quantum computers are far from capable of compromising Bitcoin's cryptography and that the associated risk is still theoretical. The exchange argued that millions of stable qubits and large-scale Shor's algorithm would be needed, giving developers time to migrate to new wallet designs, lattice-based signatures and proposals like BIP 360, with any real threat only expected to emerge around the mid-2030s to 2040s.
