Blockchain analyst Willy Woo has highlighted potential security risks associated with Bitcoin addresses starting with "bc1p," known as Taproot addresses. These addresses expose public keys, making them vulnerable to future quantum computer attacks that could compromise private keys. In contrast, "bc1q" SegWit addresses offer better protection by concealing public keys. Woo advises users to store Bitcoin in non-Taproot addresses and avoid spending until the Bitcoin network upgrades to quantum-safe protocols. The industry anticipates the arrival of "Q-Day," when quantum computers could pose a real threat, to occur post-2030.
