Quantum computing and crypto trading

The new quantum era is coming. Google's Willow chip with 105 qubits completed an impossible calculation for a classical supercomputer (it would take 10^25 years) in just five minutes . Although Bitcoin or Ethereum are still secure —millions of stable qubits would be needed to jeopardize SHA‑256 or ECDSA—, this threat is estimated to be real by 2027–2030 . Still, key players like JPMorgan and Quantinuum are already developing quantum-resistant cryptography and commercially useful random entropy generators . To operate in crypto today, concrete benefits will come from quantum models for portfolio optimization, fraud detection, and real-time analysis for trading strategies. The quantum advantage is still distant, but preparation starts now.
