Elon Musk recently asked Grok (X's AI chatbot) if Bitcoin's SHA-256 could be broken by quantum computers.
Grok’s answer: Very unlikely. Experts say the chances are near zero for the next 5 years, and still under 10% by 2035.
Why? Quantum computers today only have around 1,000 noisy qubits. Cracking Bitcoin would need about 1 trillion error-corrected qubits—nowhere close.
Grok also mentioned that in the future, Bitcoin could switch to stronger algorithms like SHA-3 or SHA-512 if needed.
Why it matters:
Tesla holds 11,509 BTC (~$1.31B), and SpaceX has ~$850M in $BTC . Elon personally owns Bitcoin too.
Bottom line: Bitcoin is safe from quantum hacking—for now.
