What makes an asset a store of value – and can crypto fit that role? Explore the idea of ‘digital gold’, why Bitcoin is often part of the conversation and how scarcity, volatility and market history shape the debate.
A store of value is an asset expected to retain purchasing power over time. The idea is that something you set aside today should still hold meaningful value in the future, even if its price moves in the short term.
Gold is a traditional example. Almost all the gold ever mined still exists and new mine output adds only a small share to that stock each year, according to the World Gold Council. Gold also differs from many commodities because it isn’t consumed through use in the same way as energy, industrial metals or agricultural products.
Those characteristics have helped make gold a long-standing reference point for the store-of-value concept. It's also sometimes discussed as an inflation hedge, although that is a related but separate idea.
What is tokenized gold and how does it work?
Bitcoin is often called ‘digital gold’ because its supply is limited and its issuance follows predetermined rules. Bitcoin’s protocol caps the maximum supply at 21 million BTC, while new bitcoin enters circulation at a decreasing rate through periodic halving events.
This fixed supply is sometimes described as ‘absolute scarcity’, to distinguish Bitcoin from physical commodities like gold. Yes, gold is naturally scarce, but its total supply isn’t capped at a known number.

Bitcoin’s supply rules are also implemented through software and network consensus rather than controlled by a central monetary authority. This programmed scarcity is another reason Bitcoin tends to be compared with scarce physical assets such as gold.
You can follow the market through the current Bitcoin price, but scarcity alone doesn’t determine what BTC will be worth. A capped supply and declining issuance describe how Bitcoin works and doesn’t guarantee future price performance.
A digital store of value is often assessed against a few core characteristics. However, each of these characteristics has strengths and limitations, so no single pillar determines whether Bitcoin is a store of value on its own.
Gold | Bitcoin | |
Form and portability | Physical metal that must be moved and shipped | Transferable digitally across borders without shipping |
Storage costs | Vaulting, insurance and custody fees can apply. This varies by storage form and jurisdiction | Depends on custody and wallet choices |
Verifiability | Authenticated physically | Transaction history recorded on a public ledger |
Scarcity | Above-ground stock is large but continues to grow via annual mine production | Protocol caps issuance at 21 million coins |
Gold and Bitcoin differ not only in their underlying characteristics, but also in how people can gain exposure to them. One notable change for Bitcoin has been the expansion of exchange-traded access.
In 2024, the SEC approved the listing and trading of shares of certain spot Bitcoin exchange-traded products on US national securities exchanges. The SEC noted that the approval wasn't an endorsement of Bitcoin itself. Spot Bitcoin exchange-traded products in the US operate within a securities regulatory framework and can provide exposure through standard brokerage accounts. This gives investors another way to access these assets without holding the underlying crypto directly.
Bitcoin’s volatility is one of the main challenges to its store-of-value case. A store of value is expected to preserve purchasing power over time, but large price swings can make that harder to rely on over shorter periods.
According to a J.P. Morgan Private Bank, Bitcoin’s annualized volatility over the prior decade was nearly 70%, compared with about 16% for global equities. Its one-year volatility also remained more than twice that of broad equities and gold. That means Bitcoin can experience much larger gains and losses over the same period, which increases the risk of needing to sell when its value is depressed.
Market behavior matters, too. During some equity selloffs, Bitcoin has traded even more like a high-risk asset. Over the past decade, it fell in 93% of four-week periods when global equities dropped 5% or more, compared with 55% for gold, according to the same J.P. Morgan analysis.
When that happens, its price can fall alongside other risk assets rather than hold steady, weakening the comparison with gold as a more established store of value.
There’s also a question of track record. Bitcoin has existed for far less time than gold, so there is limited multi-decade evidence on how well it preserves purchasing power across different inflation cycles, recessions and market regimes.
Bitcoin and gold are scarce in different ways. Bitcoin’s protocol caps total supply, while gold has no fixed maximum supply and new gold continues to enter the market through mining. The key distinction is structural: Bitcoin has a known protocol-defined ceiling, while gold supply is naturally constrained but can continue to grow.
Stablecoins are designed differently from scarcity-based assets such as Bitcoin or gold. They aim to track the value of a reference asset, often a fiat currency, rather than gain value from limited supply. That stability isn’t guaranteed. A stablecoin can trade away from its reference value and the assets backing it may not always be sufficient to meet every redemption.
In the US, the GENIUS Act was signed into law on July 18, 2025, creating a federal regulatory framework specifically for payment stablecoins. The law introduces requirements around reserves, redemption procedures and issuer oversight, but regulation doesn’t guarantee that a stablecoin will maintain its intended value.
Spot Bitcoin exchange-traded products mainly change how investors can access Bitcoin rather than its underlying supply or monetary design. They can provide exposure through standard brokerage accounts within a regulated securities framework, but that doesn’t change Bitcoin’s 21-million-coin cap or reduce its market volatility.
Once new issuance reaches that limit, no additional BTC is expected to be created under the current protocol rules. Because issuance halves roughly every four years, the last bitcoin isn't expected to be mined until around 2140. After that, miners would be paid only through transaction fees for processing and validating transactions.
Ethereum (ETH) can be discussed as a potential store of value, but its design differs from Bitcoin’s. ETH has no fixed supply cap. Part of every transaction fee is burned, so ETH's supply can shrink when network activity is high and grow when it's low. The Ethereum network is also designed to support applications, smart contracts and other activities.
