Is Bitcoin Ready for Quantum Computers? What Coinbase’s New Plan Shows

Coinbase’s new quantum-readiness plan signals that the industry is taking future cryptographic threats seriously, but it does not mean quantum computers can currently break Bitcoin. The main risk is that sufficiently powerful machines could eventually derive private keys from exposed public keys, threatening some coins and requiring a coordinated migration to quantum-resistant cryptography. Bitcoin’s security is therefore less an immediate crisis than a long-term upgrade and coordination challenge.
