The approval of spot Bitcoin ETFs in the U.S. marked a pivotal moment in financial history. On January 10, 2024, the Securities and Exchange Commission (SEC) greenlit 11 spot Bitcoin ETFs, opening the door for mainstream investors to gain exposure to Bitcoin through regulated financial instruments. Among the most prominent players are Grayscale Bitcoin Trust (GBTC), iShares Bitcoin Trust (IBIT) by BlackRock, and Fidelity Wise Bitcoin ETF (FBTC). These three have emerged as front-runners in terms of assets under management (AUM), trading volume, and investor interest.
But how do they compare? This guide breaks down the key differences between GBTC, IBIT, and FBTC across critical metrics: expense ratio, liquidity, and performance and risk, helping you make an informed investment decision.
Key Factors in Comparing Bitcoin ETFs
When evaluating Bitcoin ETFs, investors should focus on three core aspects:
1. Expense Ratio: The Cost of Ownership
The expense ratio is an annual fee charged by the fund manager to cover operational costs. It directly impacts your returns over time.
- GBTC carries a relatively high expense ratio of 1.50%—meaning you pay $15 per year for every $1,000 invested.
- IBIT offers a much more competitive rate at 0.25%, aligning with industry-low standards.
- FBTC launched with a 0% expense ratio, effectively offering free management initially. However, this will transition to 0.25% by August 2024, matching IBIT’s fee.

2. Liquidity: Ease of Trading
Liquidity determines how easily you can buy or sell shares without causing significant price swings.
- IBIT leads in liquidity, consistently capturing a large share of daily trading volume—over 47% at one point in March 2024.
- GBTC has faced persistent outflows exceeding $14 billion since its conversion to an ETF, signaling reduced investor confidence and potential liquidity strain.
- FBTC, despite strong AUM growth, trails behind IBIT in trading activity but remains competitive.
3. Performance and Risk Profile
While all three ETFs track Bitcoin’s price closely, their risk-adjusted performance varies.
- GBTC has shown higher volatility and a staggering 89.91% maximum drawdown since inception, indicating elevated risk.
- IBIT and FBTC exhibit similar volatility (~21.5%) but significantly lower drawdowns—around 16–16.8%—making them more stable options.
- In terms of Year-to-Date (YTD) returns, GBTC leads at 50.38%, followed closely by IBIT (46.94%) and FBTC (46.87%).
Despite strong performance, none have distributed dividends, as they are all less than a year old.
Understanding Bitcoin ETFs: What You Need to Know
A Bitcoin ETF allows investors to gain exposure to Bitcoin’s price movements without holding the actual cryptocurrency. Unlike direct crypto ownership, these ETFs trade on traditional stock exchanges and are regulated by the SEC, offering a layer of security and accessibility for conventional investors.
Think of it like a Gold ETF—you don’t own physical gold bars, but your investment mirrors gold prices. Similarly, a spot Bitcoin ETF holds actual BTC and aims to reflect its real-time market value.
Among the 11 approved ETFs, IBIT and GBTC dominate trading volume, with Fidelity’s FBTC rapidly gaining ground. The key structural difference lies in redemption mechanisms: IBIT supports in-kind redemptions from day one, enhancing arbitrage efficiency and price stability. GBTC initially lacked this feature, contributing to its premium/discount volatility.
Deep Dive: GBTC vs. IBIT vs. FBTC
Grayscale Bitcoin Trust (GBTC): The Pioneer Facing Challenges
Launched in 2013 as a private trust for accredited investors, GBTC was the first vehicle to offer indirect Bitcoin exposure. It transitioned to public OTC trading before finally becoming a spot ETF in 2024 after a successful lawsuit against the SEC.
Despite its pioneering status, GBTC now faces headwinds:
- High 1.50% expense ratio deters cost-conscious investors.
- Massive outflows due to institutional sell-offs—Gemini sold $1.6 billion worth of shares, and FTX liquidated its stake.
- Currently trades at $63.17 per share with $6.97 billion in AUM (as of writing).
While GBTC played a crucial role in pushing regulatory acceptance, its structural disadvantages make it less attractive compared to newer entrants.
iShares Bitcoin Trust (IBIT): The Liquidity Leader
Backed by BlackRock—the world’s largest asset manager—IBIT launched with strong momentum and quickly became the most traded Bitcoin ETF.
Key highlights:
- Low 0.25% expense ratio.
- Boasts $15.49 billion in AUM as of March 27, 2024.
- Shares trade at $14.40 with exceptional liquidity.
- Achieved 47% of total Bitcoin ETF trading volume in early March.
IBIT benefits from BlackRock’s vast distribution network and investor trust, making it a default choice for many institutional and retail investors.

Fidelity Wise Bitcoin ETF (FBTC): The Rising Challenger
Fidelity’s FBTC has quickly climbed the ranks with compelling advantages:
- Started with a 0% expense ratio, now transitioning to 0.25%.
- Holds $8.66 billion in AUM, surpassing GBTC.
- Trades at $62.06 per share with a slight 0.07% premium to NAV, indicating strong market demand.
- Known for Fidelity’s strong reputation in asset management.
Although it hasn’t overtaken IBIT in liquidity, FBTC is positioned as a serious contender, especially for investors seeking low-cost access with a trusted financial brand.
Performance & Risk Analysis
While GBTC leads in YTD performance (50.38%), its high drawdown (89.91%) and volatility raise red flags. In contrast, IBIT offers superior risk-adjusted returns, with a Sharpe-like ratio of 0.37 versus GBTC’s 0.23.
FBTC sits between the two—offering solid returns (46.87%) with moderate risk (drawdown: 16%). All three show nearly identical volatility (~21.5%), reflecting their tight correlation with Bitcoin’s price.
Investors should also monitor premium/discount to NAV:
- A premium suggests strong demand.
- A discount may indicate undervaluation or waning confidence.
Currently, FBTC trades at a slight premium, while GBTC has historically traded at steep discounts post-conversion.
Market Insights & Analyst Outlook
Analysts believe IBIT is likely to maintain dominance due to its liquidity edge and BlackRock’s market influence. Bloomberg’s James Seyffart noted that Grayscale’s outflows were partly driven by forced sales from Gemini and FTX, which could stabilize over time.
Eric Balchunas highlighted that IBIT has become one of the most actively traded assets in recent weeks. He also identified Bitwise’s BITB as another strong alternative.

Fees will continue to shape competition—Fidelity’s initial zero-fee strategy pressured BlackRock and others to keep costs low. However, liquidity remains king, and IBIT currently holds that crown.
Alternatives to Consider
Beyond GBTC, IBIT, and FBTC, other spot Bitcoin ETFs include:
- ARK 21Shares Bitcoin ETF (ARKB)
- Franklin Bitcoin ETF (EZBC)
- Bitwise Bitcoin ETF (BITB)
Each varies in fee structure and liquidity. For hands-on investors, buying Bitcoin directly via exchanges offers full control—but requires secure self-custody practices like using cold wallets.
ETFs offer convenience; direct ownership offers autonomy.
