Seeing a single headline indicating Bitcoin is holding around $71,000 would have been almost unthinkable a few years ago, never mind multiple headlines. However, this has now become something closer to a familiar data point or another milestone in an asset class that keeps forcing people to reconsider what they thought they knew. The real story isn’t Bitcoin’s price, it’s more about how many ordinary investors are finally accessing it, and through what vehicles.
The approval of spot Bitcoin ETFs in early 2024 changed everything about how the mainstream investing world engages with crypto. For the first time, anyone with a brokerage account could buy Bitcoin exposure the same way they buy a share of Apple or a Vanguard index fund. There is no wallet, no private keys, no crypto exchange account required, just a flood of institutional and retail money that came fast in a larger way than most analysts predicted.
What’s worth understanding now is that not all Bitcoin ETFs are the same. They all track the same underlying asset, that much is true, but they differ in a meaningful way on cost, size, liquidity, and custody structure. Here’s the breakdown of the five biggest Bitcoin ETFs, ranked from smallest to largest by assets under management, and what each one actually offers investors at current prices.
Bitwise Bitcoin ETF Trust
With $2.76 billion in assets under management, the Bitwise Bitcoin ETF Trust (NYSE:BITB) is the smallest fund on this list, but that doesn’t make it a bad choice. The ETF carries an expense ratio of 0.20%, one of the lowest among the spot Bitcoin ETFs approved in early 2024. If you are a cost-conscious investor, this is going to matter far more than you might think at first glance.
The Bitwise Bitcoin ETF Trust closed at $40.18 on March 16, 2026, but the 52-week range tells a fairly dramatic story with shares trading as low as $33.81 and as high as $68.74 over the past year, reflecting Bitcoin’s characteristic wide price swings. With a beta of 3.00, the fund moves roughly three times the broader market, a useful reminder that this is not a low-volatility position regardless of how it’s accessed.
Grayscale Bitcoin Mini Trust ETF
The Grayscale Bitcoin Mini Trust ETF (NYSE:BTC) is the newest fund on this list, having launched in July 2024, and it was built with a very specific purpose: to give existing Grayscale investors a lower-cost alternative to other funds without triggering a taxable event on conversion. At an expense ratio of 0.15%, it’s the cheapest Bitcoin ETF on this list and the only one without a published beta, reflecting its shorter trading history.
Assets have grown to $3.68 billion since inception, a meaningful number for a fund less than two years old. The share price closed at $32.74 on March 16, with a 52-week range hovering between $27.55 and $55.96. For investors already inside the Grayscale ecosystem looking to reduce what they’re paying in fees without stepping out of their position entirely, the Grayscale Bitcoin Mini Trust ETF is the most direct solution available.
Grayscale Bitcoin Trust ETF
Grayscale is the oldest name in this space by a wide margin, and the Grayscale Bitcoin Trust ETF (NYSE:GBTC) carries both the credibility and the cost structure that come with that history. The ETF converted to a spot ETF structure in January 2024 after years of operating as a closed-end fund, bringing $11.10 billion in assets into the new format, though significant outflows followed as investors migrated to cheaper alternatives.
The expense ratio of 1.50% is the most important number to understand before buying this ETF. This is six times what some other funds on this list are charging, and it compounds meaningfully over a multi-year holding period. The fund closed at $57.64 on March 16, with a 52-week range of $48.56 to $9912 and a beta of 2.33. For new investors, the fee gap is hard to justify unless there’s a specific tax or custodial reason to prefer this fund over its lower-cost competitors.
Fidelity Wise Origin Bitcoin Fund
Fidelity’s entry into the spot Bitcoin ETF market was always going to be significant, and the Fidelity Wise Origin Bitcoin Fund (BATS:FBTC | FBTC Price Prediction) has lived up to that expectation. With $13.33 billion of assets under management, this is the second-largest Bitcoin ETF on the market. The expense ratio at 0.25%, which puts it firmly in the lower-cost tier.
What makes the Fidelity Wise Origin Bitcoin Fund distinct is its self-custody model: unlike most Bitcoin ETFs, which rely on third-party custodians, Fidelity holds the Bitcoin directly. For institutional investors and advisors with strong Fidelity relationships, that structural difference carries a real weight. The fund closed at $64.44 on March 16, with a 52-week range of $54.21 to $110.25.
iShares Bitcoin Trust ETF
When it comes to the iShares Bitcoin Trust ETF (NASDAQ:IBIT), nothing else on this list comes close to its accumulated $55.51 billion in assets since its January 2024 launch. As a result, this is the largest Bitcoin ETF and one of the fastest-growing ETFs of any kind in market history. BlackRock’s distribution network, institutional relationships, and brand recognition drove inflows that dwarfed every competitor in the space combined.
The expense ratio hovers around 0.25%, matching that of the Fidelity Wise Origin Bitcoin Fund, but this fund’s liquidity is in a different category from the rest of the list, with daily volume regularly exceeding 60 million shares. This matters a great deal for institutional investors executing large positions. The fund closed at $41.94 on March 16, while its 52-week range hovers around $35.30 to $71.82.
For most investors seeking a straightforward, low-cost, highly liquid Bitcoin exposure through a brokerage account, this ETF is the default choice.
