Willy Woo: Bitcoin needs to guard against quantum computing threats and suggests migrating to SegWit addresses for safety

On-chain analyst Willy Woo tweeted that the future "quantum computing era" may allow public keys to be reverse-engineered into private keys, leading to asset risks. Currently, Taproot addresses starting with "bc1p" are not quantum-safe, while SegWit addresses starting with "bc1q" still have protective capabilities. He advises users to transfer BTC to SegWit or legacy format addresses and to avoid spending until an upgrade to quantum-safe protocols is completed to prevent exposure of public keys.

Woo expects that the Bitcoin network will complete its quantum-safe upgrade in about 7 years, while quantum threats may emerge as early as after 2030.
