Bitcoin as Digital Gold: Is It a Reliable Store of Value?

Bitcoin is a reliable store of value in one sense and not yet in the other. Its supply is capped and auditable, which protects against dilution, but its price has swung far more than gold's and has often moved with stocks, which is the opposite of what a safe haven is expected to do. All figures below are dated and were checked on October 20, 2026.

Key takeaways

Scarcity is verifiable: about 20.10 million of the 21 million bitcoin cap had been issued as of October 20, 2026, and the next halving is expected around April 2028.
From October 5, 2025 to June 30, 2026, bitcoin fell 53.0% (from $124,720 to $58,586), while gold futures closed 3.3% higher and the S&P 500 closed 11.7% higher over the same dates.
Over the five years to October 19, 2026, bitcoin's annualized volatility was about 52% against about 19% for gold, and its daily-return correlation with the S&P 500 was about 0.33 against 0.11 for gold.
Gold is not a calm harbor either: gold futures fell 24.9% from January 29 to July 16, 2026, and gold's correlation with stocks also rose over the past 12 months.
Bitcoin fell 64% in calendar 2022, the year US inflation peaked near 9%, while gold futures were roughly flat.

Two claims inside one phrase

"Store of value" bundles two separate promises. The first is scarcity: the supply cannot be expanded at will, so new issuance does not dilute existing holders. The second is stability under stress: the asset holds its purchasing power, or rises, when riskier assets fall. Gold has historically been associated with both. An asset can pass the first test and fail the second, so each needs its own evidence.

What the scarcity claim rests on

The scarcity half is well supported. The Bitcoin protocol cuts the block reward in half every 210,000 blocks, roughly every four years, and the Bitcoin community wiki's page on controlled supply lists the schedule: 50 BTC at launch, then 25, 12.5, 6.25, and 3.125 BTC from block 840,000 in April 2024. The same page puts the exact limit at 20,999,999.9769 BTC and estimates the last coin around 2140.

The supply issued so far can be read directly from the network. At block 972,303 (October 20, 2026), the Blockchain.com total-bitcoins query returned 20,098,843 BTC, or 95.7% of the cap, leaving about 901,000 BTC to be issued. A block-height query on mempool.space returned the same height. Blocks since the April 2024 halving have averaged about 596 seconds, so the 77,697 blocks remaining until block 1,050,000 imply the next halving, to 1.5625 BTC per block, around April 2028 (an estimate, since block timing varies).

Measure	Gold	Bitcoin
Issued so far	Not measured here	20,098,843 BTC, about 95.7% of the cap (Oct 20, 2026)
Supply rule	Not measured here	Reward halves every 210,000 blocks; cap just under 21 million
Annualized volatility, 5 years	19.2% (futures)	51.6%
Deepest drawdown, 5 years	24.9% (futures, Jan 29 to Jul 16, 2026)	76.7% (Nov 8, 2021 to Nov 21, 2022)

Scarcity is a property of supply. It says nothing about demand, and a price is set by both. That is why the second claim needs separate evidence.

How bitcoin has behaved since 2021

Correlation with stocks

An IMF blog post from January 2022 by Tobias Adrian, Tara Iyer and Mahvash Qureshi reported that the correlation between bitcoin and S&P 500 returns was 0.01 in 2017-19 and 0.36 in 2020-21, and said this limited bitcoin's diversification benefit. It also noted that bitcoin's correlation with stocks was higher than the correlation between stocks and assets such as gold.

To see whether that relationship persisted, daily closing data were downloaded for bitcoin (Coinbase, via FRED series CBBTCUSD), the S&P 500 (FRED), the Nasdaq-100 (FRED), and COMEX front-month gold futures (Yahoo Finance, GC=F). Using only days on which all series have a close, the table below shows annualized volatility and correlation with the S&P 500. The method is in the FAQ.

Window (to Oct 19, 2026)	Daily returns	Bitcoin volatility	Gold volatility	S&P 500 volatility	Bitcoin vs S&P corr.	Gold vs S&P corr.
5 years	1,253	51.6%	19.2%	17.0%	0.33	0.11
3 years	750	46.9%	21.8%	14.9%	0.18	0.14
12 months	250	42.0%	28.7%	12.7%	0.43	0.30

Two readings follow. Bitcoin's volatility has declined across the windows but remains well above gold's. And the correlation figures are unstable: bitcoin's was lower over three years than over five, and higher over the last 12 months, while gold's rose too. Because the assets close at different times of day, daily correlations are likely understated for both; they are best read as a comparison between assets, not as exact values.

The 2025-26 drawdown

FRED's daily series shows bitcoin's highest close in the period at $124,720.09 on October 5, 2025 and a low of $58,585.96 on June 30, 2026, a fall of 53.0%. By October 19, 2026 it had recovered to $81,804.35, still 34.4% below the peak. Over the same two dates, using the last closes on or before them, gold futures moved from $3,908.90 to $4,038.50 (+3.3%) and the S&P 500 from 6,715.79 to 7,499.36 (+11.7%). In this episode bitcoin lost more than half its value while stocks and gold both ended higher. The fall was not part of a broad market sell-off; over those nine months bitcoin simply failed to hold its value, which is the one thing a store of value is supposed to do.

The spot ETF channel

The SEC approved the listing and trading of spot bitcoin exchange-traded products on January 10, 2024. The then-chair's statement said the Commission "did not approve or endorse bitcoin" and called it "primarily a speculative, volatile asset." Spot funds make bitcoin exposure available through ordinary brokerage accounts. They do not change the supply rule, and bitcoin's volatility over the three years and 12 months to October 2026, most of which falls after the approval, remains well above gold's.

The inflation test in 2022

A common version of the argument is that a fixed supply makes bitcoin an inflation hedge. The 2022 data tests that. Using the seasonally adjusted CPI index on FRED, year-over-year inflation peaked at about 9.0% in June 2022. Over calendar 2022, bitcoin's close fell from $46,244.63 to $16,531.00 (-64.3%), gold futures were about flat (-0.1%), and the S&P 500 fell 19.4%. From its November 8, 2021 high to its November 21, 2022 low, bitcoin lost 76.7%.

A fixed supply guards against dilution by issuance, which is a different mechanism from consumer prices rising across the economy. Prices of an asset also depend on demand, and 2022 was a year of sharply rising interest rates: the effective federal funds rate (FRED) went from 0.07% on December 31, 2021 to 4.33% a year later, while stocks and bitcoin both fell. One year does not settle the question, but it shows scarcity alone did not preserve purchasing power in the largest US inflation spike since bitcoin launched in 2009. To see how a given rate of inflation erodes a sum over time, the purchasing power calculator runs the arithmetic.

Gold's own rough 2026

The comparison is not between a risky asset and a risk-free one. Gold futures closed at a high of $5,318.40 on January 29, 2026, then fell to $3,992.10 on July 16, 2026, a 24.9% drop. At the October 19 close of $4,160.10, gold was 21.8% below that high. Over the five-year window, that is gold's deepest drawdown, against 76.7% for bitcoin (2021-22) and 25.4% for the S&P 500 in 2022. A 25% fall is large for a haven, so gold's reputation rests on long-run behavior and breadth of demand, not on being immune to drawdowns.

One measure of that demand is official-sector buying. The World Gold Council's Gold Demand Trends for Q2 2026 (July 30, 2026) reports central-bank net purchases of 289 tonnes in the quarter, up 62% on a year earlier, though first-half purchases of 345 tonnes were the lowest for a first half since 2022.

Frequently asked questions

Did the January 2024 ETF approval make bitcoin a safer asset?

The SEC's statement said the approval covered listing and trading of spot bitcoin products and that the Commission did not approve or endorse bitcoin itself. The statement called bitcoin primarily speculative and volatile. Volatility over the three years and 12 months to October 19, 2026, shown in the table above, remains well above gold's.

How many bitcoin are left to be mined, and when is the next halving?

About 901,000 of the capped supply remained unissued on October 20, 2026, based on a total of 20,098,843 BTC at block 972,303. The next halving falls at block 1,050,000, which at the recent average block time implies around April 2028. The reward then drops from 3.125 to 1.5625 BTC per block.

How is the volatility in this article calculated?

It is the standard deviation of daily log returns multiplied by the square root of 252 trading days. Only days on which bitcoin, gold, the S&P 500 and the Nasdaq-100 all had a close were used, so bitcoin's weekend moves are not counted separately. Bitcoin trades every day of the year, so a 365-day calculation on its own series gives a similar figure (about 42% for the past 12 months).

Is bitcoin's correlation with stocks a fixed number?

No. The IMF reported 0.01 for 2017-19 and 0.36 for 2020-21, and the data above give 0.33, 0.18 and 0.43 for the five-year, three-year and 12-month windows ending October 19, 2026. The result depends on the window and the return frequency. In weekly returns over the last three years, bitcoin's correlation with the S&P 500 was 0.21 and gold's was 0.13.

Why use gold futures instead of an official gold price?

The LBMA Gold Price, the London benchmark for physical gold, could not be obtained as a free daily download when this article was checked, so COMEX front-month futures closes from Yahoo Finance are used instead. Futures settle at a different time of day from the London benchmark, and a continuous front-month series switches contracts at each roll, so individual daily figures can differ from the benchmark. Peaks and percentage moves are close but not identical; anyone needing exact benchmark values should check the LBMA directly.

A checklist for judging the claim

Separate the two questions: is supply limited, and does the price hold up when other assets fall? Ask for evidence on each.
Check the window. Correlation and volatility results change with the start date and return frequency, as the table above shows.
Compare drawdowns, not only averages: bitcoin's deepest fall in this data was 76.7%, gold's was 24.9%, and the S&P 500's was 25.4%.
Decide what job the asset is meant to do in a portfolio, then size it for the worst drawdown seen so far, not the best year.
Treat fund inflows, headlines and forecasts as context rather than evidence about behavior in a crisis.
