# Gold and bitcoin both trade below year-ago prices as Google quantum advance raises the risk to early bitcoin wallets

Bitcoin, near $82,600, is about $25,600 lower than a year ago while gold, near $4,168, is down only $86, and Google says its Willow chip now prepares key quantum states with about 40 times fewer errors.

Gold [traded at $4,168 an ounce on Friday morning](https://fortune.com/article/current-price-of-gold-10-16-2026/), $21 higher than a day earlier and $86 lower than a year ago. Silver [traded at $57.84](https://fortune.com/article/current-price-of-silver-10-16-2026/), up $1.13 on the day and more than $3 above its level a year earlier. Bitcoin [traded at $82,644.65](https://fortune.com/article/price-of-bitcoin-10-16-2026/) early on Friday, up $1,729 from the previous morning but about $25,613 below its price a year ago. Later that day the Nasdaq fell more than 2%.

The year-on-year figures matter more than the daily moves. Over 12 months, US consumer prices rose 3.7% and Brent crude approached $110. Gold roughly held its value, silver rose, and bitcoin lost about a quarter of its dollar price. In a year of war and energy-driven inflation, the monetary metals preserved purchasing power better than bitcoin. Real interest rates explain part of the difference. With the 10-year Treasury yield above 5%, holding any asset with no yield has a cost, and bitcoin has traded more like a high-beta technology stock than like a reserve asset.

A separate technical risk appeared this week. [CoinDesk](https://www.coindesk.com/tech/2026/10/16/satoshi-era-bitcoin-faces-a-bigger-quantum-threat-after-google-s-new-willow-breakthrough) reported that Google says its Willow quantum chip can now prepare the special quantum states needed for advanced calculations (magic states) with about 40 times fewer errors. That removes one of the hardware bottlenecks to any future attempt to break bitcoin's signature cryptography. The coins most exposed are early, Satoshi-era holdings whose public keys are already visible on the blockchain. Google has not claimed that such an attack is possible now. The advance shortens the time developers have to agree on a migration to quantum-resistant signatures.

Custody risk today comes from more ordinary sources. [Bitcoin Magazine](https://bitcoinmagazine.com/news/scammer-lost-bitcoin-to-ledger-thieves) reported that Chainalysis traced one victim of last week's theft targeting Ledger users and found that the victim, who lost about $5 million in bitcoin, was a scammer.

## What this means

Bitcoin is priced off liquidity and the cost of money, so a Fed still leaning toward hikes and a sell-off in leveraged technology stocks weigh on it directly. Gold is supported by central-bank and sovereign buyers who care about sanctions exposure more than yield, and the Graham Act waiver does not change their reasons. Long-term holders and protocol developers carry the quantum risk. The market has not priced it because no one can put a date on it. The danger lies in the governance problem: bitcoin's history of slow soft forks (incremental protocol upgrades), such as the years-long fight over segregated witness (SegWit), suggests that agreeing on a signature migration could take longer than the hardware timeline allows. Over the next month, the likelier pattern is that bitcoin keeps moving with the Nasdaq while gold holds a narrow range near $4,100 to $4,200. That depends on yields staying near 5%. A clear break by bitcoin above its year-ago level while equities fall would contradict this read.

## What to watch

- Bitcoin's daily correlation with the Nasdaq during the next equity sell-off. A falling correlation would be the first evidence that it is trading as a hedge.
- Formal proposals among bitcoin developers for quantum-resistant address types. A concrete proposal with a timeline would show the community treats the Willow result as urgent.
- Central-bank gold purchase data for the third quarter, which shows whether official buyers are absorbing the metal at current prices.
