Since their 2024 launch, Bitcoin (CRYPTO: BTC) ETFs have posted cumulative total inflows of $57.29 billion, with total net assets around $101.12 billion—about 6.49% of Bitcoin’s market cap, per SoSoValue. With Bitcoin trading around $77,000, investors are curious about the cheapest funds among Bitcoin ETFs.
Five funds, including Grayscale Bitcoin Mini Trust (BTC), ARK 21Shares Bitcoin ETF (ARKB), VanEck Bitcoin ETF (HODL), Morgan Stanley Bitcoin Trust (MSBT), and Valkyrie Bitcoin Fund (BRRR) are among the cheapest on the market. We ranked them by net assets, cumulative inflow strength, and value traded to see which ones are actually pulling money and trading well.
Our Ranking of the 5 Cheapest Bitcoin ETFs Right Now
Bitcoin ETFs continue to attract institutional and retail demand, but our ranking system shows that the five cheapest products have seen mixed performances over the last 30 days.
Grayscale Bitcoin Mini Trust (BTC)
Grayscale Bitcoin Mini Trust (BTC) takes the top spot, with $4.14 billion in net assets and $2.30 billion in cumulative net inflows—which puts it ahead of other low-cost competitors in size and demand at a share price of $34.
The fund’s premium-to-discount ratio—which tracks how a fund is trading in line with the actual Bitcoin it holds—is just +0.02%, which matters because wider discounts can quietly reduce returns over time. At a 0.15% fee, it is also one of the cheapest funds anywhere on the board.
Over the last 30 days, BTC has avoided any outflow periods, with its performance driven mainly by inflows or neutral sessions. The strongest day came on April 21 with $17.26 million in inflows, while the other three inflow days were less than $10 million each. Grayscale’s BTC posted another $12.60 million in daily inflows on May 14 as the CLARITY Act cleared the Senate Banking Committee stage. Since then, flows have remained flat.
The fund posted roughly $10.67 million in daily value traded, holding its own against most low-cost rivals.
ARK 21Shares Bitcoin ETF (ARKB)
ARKB ranks second thanks to strong overall inflows. The fund holds roughly $2.58 billion in net assets alongside $1.28 billion in cumulative net inflows, which also places it just behind Grayscale’s BTC among the cheapest Bitcoin ETFs.
The 30-day chart shows inflows accelerating in late April and early May, climbing above $92 million on May 5 before reversing sharply with roughly $177 million in outflows around mid-May. Despite the volatility, ARKB’s premium-to-discount ratio holds at +0.20%, which is still a strong showing in relation to its Bitcoin holdings.
With $4.64 million in daily value traded, liquidity is still solid even after the recent outflow pressure.
VanEck Bitcoin ETF (HODL)
VanEck’s HODL ranks third with $1.29 billion in net assets and $1.15 billion in cumulative inflows, showing that the fund has appreciated meaningfully since launch.
The fund’s premium-to-discount ratio is +0.25%, and the 30-day chart shows a balanced performance. After roughly $26 million in outflows in late April, HODL recovered in May with several inflow sessions reaching $17 million before posting another $7.59 million in outflows on May 18.
VanEck’s HODL trades at approximately $21.80 per share, with daily value traded of $1.52 million—lower than the top two funds, but still enough to support healthy liquidity. The fund offers a solid asset base, but at a 0.25% fee, it is the most expensive to hold of the five.
Morgan Stanley Bitcoin Trust
Per SoSoValue, Morgan Stanley Bitcoin Trust is the smallest fund in this ranking by net assets, with $270.13 million under management, but it ranks fourth because of its relatively consistent daily inflows.
The fund’s cumulative net inflows of $233.81 million make up a large share of total assets, which confirms that a meaningful portion of capital has been actively directed there in recent months.
At $22 per share, MSBT carries a premium of +0.20%. And at a 0.14% fee, it is the cheapest fund in this entire ranking—a real edge for anyone planning to hold long-term, even if its smaller size kept it from a higher spot.
Valkyrie Bitcoin Fund (BRRR)
The Valkyrie Bitcoin Fund ranks last mainly because recent performance has been defined by major inflows and outflows. BRRR holds $466.12 million in net assets—almost double that of MSBT’s—and its 30-day chart shows four consecutive daily outflows totaling over $26 million after a modest $5.81 million in inflows in late April.
When you combine that with a 0.25% fee—the highest in this group alongside HODL—and the weakest liquidity profile at just $1.43 million in daily value traded, the fund struggles to compete with Grayscale’s BTC or ARKB on either cost or liquidity.
Currently trading at $21.75, BRRR has still attracted real investor demand over time, with $318.48 million in cumulative inflows since launch.
Why Fees Matter More in 2026 Than Ever
Bitcoin ETF fees matter more in 2026 because they quietly eat into your returns over time. A 0.25% fee—like HODL’s and BRRR’s—keeps charging you daily for holding the fund, and compounded over years, it drags down your total profit as a long-term investor.
With most Bitcoin ETFs tracking the same asset, performance differences are minimal, which leaves fees as the most controllable variable. For long-term holders, the gap between a 0.14% fund like MSBT and a 0.25% one like BRRR compounds into real money over a decade—which makes checking the fee before you buy the simplest edge available.
