What are Bitcoin's quantum vulnerabilities?

Mainly old P2PK addresses exposing public keys directly, crackable by Shor's algorithm on future quantum hardware.

When could quantum computers threaten Bitcoin?

Researchers eye 2030 for viable threats, but no danger today — needs massive, error-free qubits.

How will Bitcoin fix quantum risks?

Options: burn vulnerable coins, limit spending rates, or adopt post-quantum signatures via consensus upgrades.
