What is BIP-360 and does it make Bitcoin quantum-proof?

BIP-360 proposes Pay-to-Merkle-Root outputs to cut Taproot vulnerabilities via soft fork. It reduces risks for active addresses but leaves ~8% dormant supply exposed—no full quantum signatures yet.

How long until quantum computers break Bitcoin?

Bernstein estimates 3-5 years for viable threats. Google's models suggest under 500K qubits could crack keys in minutes, but error-corrected machines are years off.

Should I move my Bitcoin now to avoid quantum risk?

If your coins are dormant >1 year, consider sweeping to fresh quantum-aware addresses. Active wallets are safer; watch for BIP-360 rollout.
