Cryptocurrency has failed as a currency but succeeded as an asset class

What's this about?

People disagree about whether crypto has failed as money but won as an asset people buy and sell.

Crypto means digital money, such as Bitcoin, that works online.

What supporters say

• Most people do not use Bitcoin to buy lunch, pay bills, or set shop prices.
• Bitcoin’s price can jump or fall fast, so shops may lose money after they accept it.
• In El Salvador, many people kept using cash and US dollars instead of Bitcoin.
• Crypto now has big trading sites, safe storage firms, and more links to the wider money system.

What critics say

• The word “failed” may go too far, since some people still use crypto to send or receive money.
• Bitcoin’s role as an asset does not mean it works well for every person or every savings plan.
• Its price swings can cause big losses, so it can be a risky thing to own.
• Some past tests found benefits from adding Bitcoin to a mix of assets, but those results depend on the time tested.

The bottom line

The claim mostly fits the facts: crypto has not become daily money for most people.

But it has grown much more as an asset that people trade and invest in, with real risks.

Cryptocurrency has not become ordinary money for most people, but it has built a far larger role as a traded and investable financial product. That makes the claim broadly right in relative terms—though the words “failed” and “succeeded” need important limits.

The case for

The strongest evidence is that Bitcoin has not gained broad, lasting use for everyday purchases or as a way shops routinely set prices. Its sharp price swings make it hard to use as a practical means of payment: a merchant who accepts Bitcoin may find its value has changed significantly before the transaction is settled. Research indicates that this volatility discourages both spending and acceptance, even as it makes Bitcoin more prominent as an investment vehicle. 1

El Salvador’s experiment with Bitcoin as legal tender offers a notable real-world test. Despite government incentives and an official digital wallet, surveys found that cash and US dollars remained dominant. Many people who received Bitcoin incentives converted them quickly or stopped using the service, rather than adopting Bitcoin for regular transactions. 1

At the same time, crypto has developed much of the machinery associated with an investable market. It trades continuously around the world, has established pricing and exchange networks, and is supported by custody and trading services. International bodies including the IMF and the G20’s Financial Stability Board describe crypto as increasingly tied to the wider financial system, with consequences for capital flows, investment and financial stability. Institutional investors have also shown interest in digital-asset trading, custody and related services. 2

Some historical portfolio studies add support for Bitcoin’s investment role. They find that, in selected periods and under particular portfolio strategies, adding Bitcoin could improve diversification, hedging or risk-adjusted returns. 3 But these results are conditional: they depend on the time period studied, the data used and how portfolios were rebalanced. They show potential usefulness in a portfolio, not a guarantee of future gains, stable value or safety in a downturn.

The case against

Calling cryptocurrency a total currency failure would go too far. Bitcoin and other crypto networks are used for payments, remittances, savings, fundraising and activities where resistance to censorship matters. A review of Bitcoin use cases identifies these roles, while research from the Bank for International Settlements finds crypto can facilitate cross-border transfers shaped by financial and geographic conditions. 4

These uses do not amount to mass adoption for daily shopping. But they do show that crypto retains currency-like and settlement functions in specific settings. And Bitcoin’s problems as a payment tool cannot automatically be applied to every crypto product. Stablecoins and other payment arrangements may have different features, while international research covers Bitcoin, Ether and stablecoins—not Bitcoin alone. 5

There are also major reasons not to treat crypto’s market growth as proof that it has become a mature or dependable asset class. Trading volume, market value and institutional attention demonstrate demand for speculation and investment, but they do not establish fundamental value, deep liquidity or reliable long-term returns. IMF and G20/FSB work continues to flag leverage, contagion, investor-protection and financial-stability risks. The FTX collapse, meanwhile, exposed failures in exchange governance, custody and conflicts of interest (see Figure 2). 6

Bitcoin’s reputation as a defensive store of value is especially uncertain. Some research finds inflation-hedging properties over certain time horizons, but not dependable protection during market stress. Other studies find that hedge and safe-haven effects vary widely depending on the market, period and crisis examined.

The bottom line

The evidence supports a comparative conclusion with high confidence: Bitcoin and cryptocurrency have been more successful as speculative and portfolio-oriented financial assets than as routine currencies. Ordinary retail use remains limited, while financial-market infrastructure, trading activity and investor interest have expanded substantially.

But the claim should not be read as saying crypto has no monetary role, or that it has conclusively become a safe, durable asset class. It still serves payment and transfer needs in particular contexts, and its investment benefits remain uneven and dependent on conditions. The biggest unanswered question is whether those historical portfolio gains and evolving payment uses will persist as technology, regulation and market conditions change.
