Satoshi-era bitcoin faces a bigger quantum threat after Google’s new Willow breakthrough

Google's new Willow quantum chip can prepare the special quantum states needed for advanced calculations with roughly 40 times fewer errors, lowering a key hardware barrier that would matter for any future attempt to crack bitcoin wallets. The story focuses on Satoshi-era coins, whose early pay-to-public-key outputs are considered more exposed to a hypothetical quantum attack. No wallet is at risk today, but traders holding long-dormant coins may weigh the long-term security narrative, making this a modest negative for BTC sentiment rather than an immediate price driver.
