google’s 2029 deadline is an internal migration target. it has NOTHING to do with when Bitcoin might be broken. tying them together is misleading. the “6.26m BTC at risk” claim is false. only early P2PK addresses have permanently exposed public keys. standard addresses don’t expose keys unless reused. counting all is fearmongering. the timeline also contradicts itself. it claims 2 to 5 years, then says mainstream estimates are 2030s to 2040s. today’s quantum machines have a few thousand noisy qubits, breaking ECDSA would need millions of stable qubits. applying HNDL to Bitcoin is a basic mistake. Bitcoin uses signatures, not encryption. there is no store now break later path. the RSA vs ECDSA point is reversed. under Shor’s algorithm, ECDSA is easier to break than RSA. calling post quantum signatures “larger” understates it. Dilithium is over 30x bigger than ECDSA, enough to impact block economics. the quantum threat is real but not imminent. PQC paths are clear and the community is already alert. no need to panic.(Yishi)
