The world of digital assets operates 24/7, 365 days a year—unlike traditional financial markets. This fundamental mismatch is creating a growing dilemma for U.S. asset managers and regulators as they inch closer to potentially approving a cryptocurrency exchange-traded fund (ETF). While investors eagerly await a green light from the Securities and Exchange Commission (SEC), one critical issue looms large: market hours.
ETFs trade on regulated exchanges during standard business hours, typically Monday through Friday. But Bitcoin, Ethereum, and other major cryptocurrencies don’t pause for weekends or holidays. This creates a structural disconnect—one that could leave investors exposed during volatile off-market periods.

The Sunday Effect: A Weekend Risk for ETF Investors
Imagine this: Bitcoin drops 15% on a Saturday night. If you're invested in a Bitcoin ETF, you’re locked in—no selling, no hedging—until the market reopens on Monday. Conversely, if prices surge over the weekend, you can’t capitalize until regular trading resumes.
Carol Alexander, a finance professor at the University of Sussex, calls this phenomenon the “Sunday effect.” It refers to the sharp price movements between Sunday and Monday, often amplified by the fact that many U.S. financial professionals are offline during weekend hours.
“The crypto market is 24/7, so there’s no role for an open-ended fund that you can’t get out of during the weekend,” Alexander argues. “If investors are trapped during a downturn, class-action lawsuits could follow.”
This structural limitation raises serious concerns about investor protection—especially during periods of high volatility. And while some believe the SEC’s hesitation is justified, others argue that informed investors should understand the tradeoffs.
Canada Leads the Way with Live Crypto ETFs
While the U.S. debates, Canada has already taken action. In February 2025, it launched the first crypto ETF in North America: Purpose Bitcoin ETF (BTCC). Within just two months, BTCC amassed over 1 billion Canadian dollars in assets, demonstrating strong investor demand.
Greg Taylor, Chief Investment Officer at Purpose Investments, acknowledges that assets later dipped to around $900 million following Bitcoin’s mid-May correction—but he remains confident in the product’s long-term value.
“Crypto ETFs bring digital assets into the mainstream,” Taylor says. “They transform what was once a niche, tech-driven investment into something accessible through traditional brokerage accounts.”
Since BTCC’s debut, Canada has seen a wave of new crypto ETFs, including funds tracking Ethereum and multiple Bitcoin offerings from competitors like CI Financial.
Why ETFs Matter: Simplicity, Liquidity, and Tax Efficiency
For most U.S. investors, accessing crypto remains cumbersome. Options include:
- Buying directly from individuals (high risk)
- Using exchanges like Coinbase or Gemini (requires technical know-how)
- Investing through private funds for accredited investors (high barriers to entry)
These methods often come with high premiums, limited liquidity, and complex tax implications. More importantly, integrating them into a diversified portfolio can be challenging.
Enter the ETF model.
Designed to track underlying assets closely while offering high liquidity and tax efficiency, ETFs simplify access. Investors can buy shares through familiar platforms—no wallets, private keys, or exchanges required.
Matt Hougan, Chief Investment Officer at Bitwise Asset Management, explains: “Each current method has pros and cons. But an ETF offers a regulated, transparent path that fits seamlessly into retirement accounts and taxable portfolios.”
Bitwise filed its first Bitcoin ETF application in 2019—a sign of early confidence in the model.
Liquidity Tradeoff: The 24/7 Market vs. 5-Day Trading
Despite their benefits, crypto ETFs aren’t perfect. One major compromise? Lack of 24/7 liquidity.
“An ETF isn’t going to be for every investor,” Hougan admits. “One of the tradeoffs you make is that you don’t have round-the-clock access.”
However, Purpose Investments mitigates this by partnering with Canadian market makers to ensure tight bid-ask spreads—as low as one cent—by continuously monitoring Bitcoin’s price movements, even when markets are closed.
Still, critics like Alexander worry about systemic risks. Could a weekend crash trigger panic selling on Monday? Could delayed reactions amplify market instability?
These concerns echo broader regulatory hesitations—not just about trading hours, but also about systemic risk, market manipulation, and the gamification of finance, exemplified by events like the GameStop surge earlier in 2025.

Gold and Oil Precedents: Lessons from Commodity ETFs
Taylor draws parallels between crypto ETFs and existing commodity ETFs—such as those for gold or oil—which also track assets traded globally around the clock.
“Investors in gold ETFs understand they can’t trade after hours,” he says. “The same awareness should apply to crypto. Education is key.”
While commodities do experience volatility, they generally lack the extreme swings seen in digital assets. Bitcoin’s price can shift dramatically based on tweets, regulatory rumors, or macroeconomic data—often when U.S. markets are closed.
Yet Taylor believes investor education can bridge the gap: “Awareness is really key—to make sure underlying investors understand the limitations of an ETF.”
The Road Ahead: Will the SEC Approve?
As of now, the SEC has not approved any U.S.-listed crypto ETFs. Applications from major players like Fidelity, WisdomTree Investments, and others remain under review.
The core challenges remain:
- Market hour misalignment
- Price volatility during off-hours
- Custody and security concerns
- Regulatory clarity on asset classification
But demand is undeniable. The success of Canadian ETFs proves there’s appetite for regulated, easy-to-use crypto investment products.
Hougan remains optimistic: “The benefits of the ETF structure—transparency, liquidity, integration with existing financial systems—are immense.”
Frequently Asked Questions (FAQ)
Q: Why can’t crypto ETFs trade 24/7 like Bitcoin?
A: ETFs are listed on traditional stock exchanges (like NYSE or NASDAQ), which operate only during set business hours—unlike decentralized crypto markets.
Q: What happens to a Bitcoin ETF if prices drop over the weekend?
A: Investors cannot sell until markets reopen Monday. The fund’s net asset value (NAV) will reflect weekend price changes when trading resumes.
Q: Are crypto ETFs safer than buying Bitcoin directly?
A: They offer regulatory oversight and eliminate custody risks (no need to manage private keys), but introduce market timing risks due to limited trading hours.
Q: How do Canadian crypto ETFs handle weekend volatility?
A: They use market makers to estimate fair value and maintain tight spreads, though actual trading still pauses when exchanges are closed.
Q: Can I hold a crypto ETF in my retirement account?
A: Yes—once approved in the U.S., crypto ETFs could be held in IRAs and 401(k)s, offering tax advantages over direct crypto ownership.
Q: Will a U.S. crypto ETF boost Bitcoin adoption?
A: Absolutely. Easier access via brokers and banks could bring institutional and retail investors into the ecosystem at scale.

Final Outlook: Bridging Two Financial Worlds
The clash between 24/7 crypto markets and traditional trading hours isn’t just technical—it’s philosophical. It reflects a broader shift in how we define accessibility, liquidity, and investor protection.
While challenges remain, the momentum toward approval is building. With Canada proving the model works and U.S. firms preparing for launch, it may only be a matter of time before American investors gain regulated access to crypto through ETFs.
When that day comes, understanding the tradeoffs—especially around market hours, liquidity, and volatility—will be essential for every investor.
