A technical debate erupted on X after on-chain analyst Willy Woo published what he called a “DUMMIES GUIDE TO BEING QUANTUM SAFE,” urging Bitcoin holders to migrate coins away from Taproot addresses (bc1p) to SegWit bc1q or older P2PKH/P2SH formats and to avoid spending until post-quantum protections are available.
Woo characterized industry expectations as “2030 onwards” for the arrival of “Q-Day,” while stressing that standards for quantum resistance are already rolling out across the wider cryptography space.
In Schnelli’s view, the moment any spend is broadcast, “your pubkey hits the mempool. A quantum attacker could crack your key and RBF double-spend before your transaction confirms (~10 minutes).” He concluded: “It’s a smart precaution, not a permanent solution.”
At press time, BTC traded at $104,693.
