July 21, 2026: Bitcoin (BTC) climbs back above $65,000. According to Gate market data, Bitcoin traded around $65,622 that day, up about 0.9% over 24 hours, with trading volume surging to roughly $28.53 billion. The total market cap rebounded to approximately $1.307 trillion. Over the past week, the Bitcoin price rose 3.73%; over the past 30 days, it edged up 0.56%. However, on a one-year basis, it remains down about 44.85% from the all-time high above $126,000 set in October 2025.
During the same period, spot gold fluctuated near $4,000 per ounce. On July 21, spot gold traded in the $4,007 to $4,073 per ounce range. Since the start of the year, gold has declined about 7%, but over the past 12 months it still holds a gain of roughly 19%.
Bitcoin and gold—two widely discussed "store of value" assets—have followed distinctly different price paths in 2026. The comparison becomes even more intriguing at the ETF level. In a recent report, Bloomberg Senior ETF Analyst Eric Balchunas noted that Bitcoin ETFs are likely tracking the historical trajectory of gold ETFs over the past two decades: "stunning rallies, painful drawdowns, and recovery phases that require extreme patience."
What’s the underlying logic behind this view? What lessons can the history of gold ETFs offer Bitcoin ETFs? This article takes a data-driven approach to systematically break down the three-phase evolution of gold ETFs over twenty years, the current state of Bitcoin ETFs, and the key structural similarities and differences between the two.
Gold ETFs Over Two Decades: Three Historical Phases
In November 2004, the world’s first gold ETF—SPDR Gold Trust (ticker: GLD)—was listed on the New York Stock Exchange. Before that, investors could only gain gold exposure through buying bullion, gold mining stocks, or futures contracts. The launch of GLD marked the first time that physical gold became accessible to mainstream portfolios in a securitized form.
Looking back at GLD’s more than 20-year history, its development can be divided into three distinct phases.
Phase One: Rapid Growth (2004–2011)
GLD’s debut coincided with a long-term bull market in gold. From 2004 to 2011, gold prices soared from about $400 per ounce to over $1,900 per ounce—a gain of more than 370%. GLD’s assets under management (AUM) expanded explosively. In 2011, GLD briefly surpassed SPY, the S&P 500 ETF, to become the world’s largest ETF.
This phase wasn’t driven by changes in gold’s fundamentals, but rather by a combination of macro factors: the Federal Reserve’s quantitative easing after the 2008 global financial crisis, persistently low real interest rates, and shaken investor confidence in the US dollar. Gold ETFs offered extremely low holding costs and high liquidity, enabling both institutional and retail investors to enter the market at scale.
Phase Two: Major Correction (2011–2015)
After peaking in 2011, GLD entered a prolonged downtrend. From 2011 to 2015, gold prices fell from over $1,900 per ounce to about $1,050 per ounce—a drop of more than 40%. GLD’s AUM shrank sharply from a peak of around $76.7 billion.
The core logic of this correction: the US economy recovered, the Fed began planning an exit from quantitative easing, the dollar strengthened, and real interest rates rose. As a non-yielding asset, gold became more expensive to hold during rising rate cycles, prompting large-scale capital outflows. Balchunas notes that after GLD’s 2011 peak, it took nearly eight years to return to similar levels, with inflows slowing dramatically and market attention waning.
Phase Three: Long-Term Asset Accumulation (2016–Present)
Since 2016, gold has entered a long, choppy upward channel. Despite several corrections, each cycle’s lows have trended higher, with new highs continually set. By 2026, gold ETFs’ total AUM had grown to roughly $160–$235 billion. In July 2026, gold prices topped $4,000 per ounce, up about 280% from the 2015 low.
Balchunas’s key observation: after each bull-bear cycle, gold ETFs have set new all-time highs. This suggests that as long as long-term demand persists, each bull market can push the price ceiling higher—even after years of consolidation.
The State of Bitcoin ETFs: Scale, Drawdowns, and Stress Tests
Spot Bitcoin ETFs were approved for trading in the US in January 2024. In less than two years since, Bitcoin ETFs have charted an even steeper growth curve than gold ETFs.
Scale: Surpassing $100 Billion in the First Year
BlackRock’s IBIT is the world’s largest spot Bitcoin ETF. In October 2025, when Bitcoin hit its all-time high above $126,000, IBIT’s AUM briefly reached $100 billion. Balchunas points out that IBIT spent "only a few hours" above this milestone.
As of July 21, 2026, total net assets of spot Bitcoin ETFs stood at $79.16 billion, about 6.04% of Bitcoin’s total market cap, with cumulative net inflows of $51.58 billion. IBIT’s AUM was around $60 billion.
Drawdown: About a 48% Price Correction
From its October 2025 peak above $126,000, Bitcoin’s price fell to about $65,000 by July 2026—a drawdown of roughly 48%. This is comparable in magnitude to the 40%+ correction gold ETFs experienced from 2011 to 2015.
Fund Flows: Ongoing Stress Test
In May and June 2026, spot Bitcoin ETFs saw sustained outflows totaling around $7 billion. In July, flows reversed. For the week ending July 17, spot Bitcoin ETFs recorded net inflows of $75.7 million, ending eight consecutive weeks of outflows (totaling over $8.2 billion). On July 20, spot Bitcoin ETFs posted a single-day net inflow of $227 million, marking the fifth straight day of net inflows.
On July 20, IBIT had a single-day net inflow of $116 million, ARKB saw $72.7 million, FBTC $24.1 million, while GBTC faced a net outflow of $45.4 million.
According to Bernstein, in 2026, combined net inflows from corporate treasuries, asset allocators, and spot Bitcoin ETFs totaled about $10 billion—a sharp drop from $60 billion in 2025. For 2026 overall, spot Bitcoin ETFs saw net outflows of $5.5 billion, with total AUM at $74 billion.
These figures indicate that Bitcoin ETFs are undergoing a classic "stress test"—inflows during rallies, outflows during declines, with investor sentiment and price reinforcing each other in both directions. This closely mirrors the experience of gold ETFs from 2011 to 2015.
Gold ETFs vs. Bitcoin ETFs: Structural Similarities and Differences
While Balchunas believes Bitcoin ETFs may "mirror" the historical path of gold ETFs, there are significant structural differences. These differences mean Bitcoin ETFs could both repeat gold’s playbook and forge their own path.
Similarities: Securitized Non-Yielding Store of Value
Balchunas’s core argument: both gold and Bitcoin are "non-yielding store of value" assets packaged as ETFs. They don’t generate cash flow—unlike stocks (profits), bonds (coupons), or government-backed assets. Price movement is driven solely by investor sentiment and supply-demand dynamics. Both have "limited supply"—gold’s above-ground stock grows slowly, while Bitcoin’s total supply is capped at 21 million. When demand surges, rigid supply amplifies price gains; when demand wanes, price corrections are equally sharp.
Difference 1: Volatility
Bitcoin’s volatility is far higher than gold’s. Over the past year, Bitcoin fell from above $126,000 to about $65,000—a 48% drop. In the same period, gold dropped from roughly $4,800 per ounce to about $4,000—a 17% decline. Bitcoin’s volatility is roughly three times that of gold. This means Bitcoin ETF investors must tolerate much higher volatility than gold ETF holders, but also have greater upside potential.
Difference 2: Adoption Speed
Gold ETFs took over 20 years to accumulate $160–$235 billion in AUM. In less than two years, Bitcoin ETFs have seen cumulative net inflows above $51.5 billion and total net assets near $80 billion. The adoption speed is unprecedented.
Balchunas predicts that if the current growth continues, Bitcoin ETFs’ AUM could reach three times that of gold ETFs within three to five years. The key assumption: Bitcoin ETFs are still in the early stages of penetrating traditional brokerage channels. As Bitcoin ETFs become as easy to trade as regular stocks on traditional platforms, investors can avoid the hassle of private keys, seed phrases, and self-custody wallets—significantly lowering the entry barrier.
Difference 3: Holder Structure
Data shows that after the major correction, only about 10% of Bitcoin ETF holders remain in profit, compared to about one-third for gold ETFs. This suggests a higher proportion of short-term speculative capital in Bitcoin ETFs, while gold ETFs have a larger share of long-term allocations. However, long-term Bitcoin holders have not yet turned net sellers—a fact some analysts see as a positive signal.
Long-Term Scenarios: Three Possible Paths for Bitcoin ETFs
Based on the historical data of gold ETFs and the current state of Bitcoin ETFs, we can envision three long-term scenarios for Bitcoin ETFs.
Scenario 1: Fully Replicating the Gold Path
In this scenario, Bitcoin ETFs strictly follow the "rapid growth—major correction—long-term accumulation" model of gold ETFs. Currently, they are in the latter part of the second phase (major correction). Based on gold’s experience, this phase could last several years. Then comes the third phase, with Bitcoin prices gradually rising through cycles, each high surpassing the previous one. The core support for this scenario is Bitcoin’s hard supply cap and the long-term trend of institutional allocation.
Scenario 2: Accelerated Gold Path
Given the much faster adoption of Bitcoin ETFs, the correction phase may be shorter and the recovery faster. Balchunas forecasts that Bitcoin ETFs’ AUM could reach three times that of gold ETFs within three to five years. In this scenario, each cycle for Bitcoin ETFs could play out over years rather than decades. The key assumption: institutional infrastructure (custody, compliance, liquidity) matures much faster than it did in the gold ETF era.
Scenario 3: An Independent Path
Bitcoin and gold differ fundamentally in value logic. Gold’s value is rooted in millennia of human consensus, while Bitcoin’s value is built on the consensus and technological faith of digital natives. The investor base, use cases, and macro drivers are all notably different. Bitcoin could chart a completely different long-term course from gold—potentially higher, or lower. This scenario carries the greatest uncertainty.
Conclusion
Gold ETFs have proven over two decades that non-yielding store-of-value assets can succeed in ETF form—from rapid growth to major corrections, and then to long-term asset accumulation, with each cycle raising the price ceiling. Bitcoin ETFs are following a similar script: surpassing $100 billion in their first year, experiencing a roughly 48% price correction, and entering a stress test phase for investors.
Bloomberg analyst Eric Balchunas provides a valuable analytical framework: the 22-year history of gold ETFs may be the closest roadmap available for Bitcoin ETF investors. But a roadmap is not a route—the ultimate direction for Bitcoin ETFs will depend on the depth of institutional adoption, the evolution of investor structure, and whether Bitcoin’s value as a digitally scarce asset can withstand the test of time.
As of July 21, 2026, Bitcoin traded at $65,975.4, up 3.34% over 24 hours, with a market cap of $1.32 trillion and neutral market sentiment. Spot Bitcoin ETFs had total net assets of $79.16 billion, with five consecutive days of net inflows. The stress test continues, and history is being written.
FAQ
Q: What’s the core difference between Bitcoin ETFs and gold ETFs?
The underlying assets differ—gold ETFs are backed by physical gold, while Bitcoin ETFs are backed by digital assets. In terms of value logic, gold serves as a safe haven and inflation hedge, while Bitcoin is a digitally scarce asset. Bitcoin is much more volatile than gold. Gold ETFs have a 20+ year history; Bitcoin ETFs are still in their early days. Institutional acceptance is mature for gold, but growing rapidly for Bitcoin.
Q: How large are Bitcoin ETFs right now?
As of July 21, 2026, spot Bitcoin ETFs had total net assets of about $79.16 billion, accounting for roughly 6.04% of Bitcoin’s total market cap, with cumulative net inflows of about $51.58 billion. BlackRock’s IBIT holds about $60 billion in AUM.
Q: Why are Bitcoin ETFs said to be undergoing a "stress test"?
Bitcoin’s price has fallen about 48% from its all-time high above $126,000 in October 2025 to about $65,000. In May and June 2026, ETFs saw outflows of around $7 billion. The positive feedback loop of inflows during rallies and outflows during declines is testing investor confidence and holding power.
Q: What’s the long-term outlook for Bitcoin ETFs?
Bloomberg analyst Eric Balchunas believes Bitcoin ETFs may replicate the 22-year trajectory of gold ETFs—cycles of rapid growth, major corrections, and long-term accumulation, with each high moving higher. He expects that if current growth continues, Bitcoin ETFs’ AUM could reach three times that of gold ETFs within three to five years.
Q: Is now a good time to buy Bitcoin ETFs?
This article does not constitute investment advice. Bitcoin ETFs are far more volatile than gold ETFs and are currently in a stress test phase with price corrections and fluctuating fund flows. Investors should assess their own risk tolerance, investment horizon, and asset allocation needs, and seek professional financial advice if necessary.
