Glassnode Study Flags $469 Billion in Bitcoin Exposed to Quantum Risk

The latest Glassnode analysis reveals 6.04 million BTC—roughly 30% of supply and valued at $469 billion—now carry exposed public keys vulnerable to future quantum attacks. The development follows Project Eleven’s early-May warnings that Q-Day could arrive by 2030 and Citi’s May 18 assessment that 6.5–6.9 million BTC face outsized risk due to Bitcoin’s slow governance. The U.S. Department of Commerce’s $2 billion quantum investment announced May 21 has accelerated hardware timelines, while Fireblocks and Charles Hoskinson have framed migration as a coordination challenge. AmericanFortress’s soft-fork proposal offers a potential path to shield dormant coins without mass migrations. Market focus is now shifting to post-quantum upgrades and custody adjustments.
