🚨 YOUR $BTC PRIVATE KEYS COULD BE CRACKED IN 9 MINUTES. Google researchers just revealed a major quantum breakthrough that could break crypto security far sooner than expected. They improved Shor’s algorithm by ~20x, meaning a future quantum computer (~500K qubits) could: • Crack private keys in ~9 minutes • Roughly match Bitcoin’s block time • Turn mempool attacks into a real threat Timeline shift is the scary part. They now point to ~2029 for this level of power, not the mid-2030s. Instead of publishing the full method, they only released a proof it exists. That almost never happens. CZ’s take: “No need to panic… crypto just needs to upgrade to post-quantum algorithms.” The clock is already ticking. #GoogleStudyOnCryptoSecurityChallenges
