Quantum computing is often seen as Bitcoin's unsolvable problem. But Satoshi already thought through it. In 2010. @BitcoinMagazine just surfaced the only public comment Satoshi ever made on quantum computing risk to $BTC. Back in 2010, a user named "llama" asked: what happens if quantum computers compromise Bitcoin's signatures? Does it make BTC worthless? Satoshi's full response: "True, if it happened suddenly. If it happens gradually, we can still transition to something stronger. When you run the upgraded software for the first time, it would re-sign all your money with the new stronger algorithm." The danger is speed. A quantum breakthrough that happens gradually gives Bitcoin time to upgrade its cryptography. A sudden one doesn't. Fifteen years later, quantum computing is still developing gradually. The network still has time. Satoshi's 2010 answer is basically the same roadmap cryptographers are working toward today: Transitioning to quantum-resistant algorithms, re-signing wallets with stronger keys. He saw it coming. He had a plan. And the plan still makes sense.

Google Quantum AI's whitepaper (Mar 30, 2026): "Securing Elliptic Curve Cryptocurrencies against Quantum Vulnerabilities." Key: Breaking 256-bit ECDSA (used in BTC, ETH, most chains) now estimated at ~1,200 logical qubits + 70-90M gates—20x fewer resources than prior models. Fast-clock quantum systems could do it in minutes, enabling real-time "on-spend" attacks within BTC's 10-min blocks. Broader impact: Risks all EC-based encryption (banks, military, web). Urges full PQC migration ASAP, with Google targeting 2029 internally. Paper: quantumai.google/static/site-as…







VanEck Bitcoin ChainCheck, key takeaways: Key takeaways >Bitcoin consolidates after sharp drawdown: The 30-day average bitcoin (BTC) price fell 19%, but spot prices stabilized as realized volatility dropped from 80 to 50 and futures funding rates declined from 4.1% to 2.7%. >Options signal peak defensiveness: The put/call open interest ratio averaged 0.77, its highest since June 2021, while put premiums relative to spot volume hit an all-time high of 4 basis points. >Onchain activity and miner selling remain subdued: Transfer volume fell 31%, daily fees dropped 27%, and long-term holder distribution slowed, while miners sold roughly all newly issued BTC.
