Grayscale Bitcoin Trust (GBTC) review 2026: 1.5% expense ratio, discount history, ETF conversion. Should you still hold it or switch to IBIT/FBTC? Full analysis.
The January 2024 approval of spot Bitcoin ETFs in the United States was a landmark moment. For the first time, American investors could get direct Bitcoin price exposure through a standard brokerage account — no crypto exchange, no seed phrase, no custody headaches. By 2026, Bitcoin ETFs collectively hold over $60 billion in assets and trade billions of dollars daily.
But not all Bitcoin ETFs are the same. Fees, custody arrangements, tracking error, liquidity, and tax treatment vary. Here's exactly what you need to know to pick the right one.
How Bitcoin ETFs Work
A spot Bitcoin ETF holds actual Bitcoin as its underlying asset. When you buy shares, the fund manager buys Bitcoin on your behalf (through an authorized participant). When you sell, they sell Bitcoin.
This differs from Bitcoin futures ETFs (like the BITO ProShares fund), which hold futures contracts rather than actual Bitcoin. Futures ETFs have structural drag from rolling contracts and typically track Bitcoin price less accurately. For most investors, spot ETFs are strictly better than futures ETFs.
US Spot Bitcoin ETFs: The Big Players
iShares Bitcoin Trust (IBIT) — The Category Leader
iShares Bitcoin Trust (IBIT) from BlackRock is the most important Bitcoin ETF ever created.
- Ticker: IBIT (NASDAQ)
- Expense ratio: 0.25% (reduced from 0.30% introductory rate)
- AUM: $40+ billion (largest Bitcoin ETF globally)
- Custodian: Coinbase Custody
- Daily volume: $1-2+ billion
Why IBIT dominates: BlackRock's distribution network, institutional trust, and the brand recognition that major pension funds, family offices, and wealth managers require before allocating. IBIT also benefits from tight bid-ask spreads due to massive liquidity.
For most investors who want the simplest, most liquid, most institutionally vetted option: IBIT is the default choice.
Fidelity Wise Origin Bitcoin Fund (FBTC)
Fidelity Wise Origin Bitcoin Fund (FBTC) is the second-largest US spot Bitcoin ETF and Fidelity's entry.
- Ticker: FBTC (NYSE Arca)
- Expense ratio: 0.25%
- AUM: $10+ billion
- Custodian: Fidelity Digital Assets (self-custody — Fidelity holds its own Bitcoin)
- Daily volume: $300-700M
FBTC's key differentiator: Fidelity custodies its own Bitcoin rather than using Coinbase. For investors who want Bitcoin held by a 75-year-old financial institution with its own digital asset infrastructure, this is meaningful.
Fidelity customers can also access FBTC directly through Fidelity's platform with no transaction fees.
Bitwise Bitcoin ETF (BITB)
Bitwise Bitcoin ETF (BITB) from Bitwise Asset Management is the Bitcoin-native fund manager's entry.
- Ticker: BITB (NYSE Arca)
- Expense ratio: 0.20% (lowest among major US funds)
- AUM: $3+ billion
- Custodian: Coinbase Custody
- Unique feature: 10% of profits donated to Bitcoin open-source development
BITB is the cost leader at 0.20%. For long-term holders sensitive to fees, even the 5 basis point difference vs. IBIT compounds significantly over decades.
Bitwise is also the most Bitcoin-focused asset manager of the group — Bitcoin is their core business, not a product extension.
ARK 21Shares Bitcoin ETF (ARKB)
ARK 21Shares Bitcoin ETF (ARKB) is the collaboration between Cathie Wood's ARK Invest and 21Shares.
- Ticker: ARKB (Cboe BZX)
- Expense ratio: 0.21%
- AUM: $2+ billion
- Custodian: Coinbase Custody
Similar structure to other ETFs. The ARK brand attracts a specific investor type — those already in ARK's thematic ETF ecosystem.
VanEck Bitcoin ETF (HODL)
VanEck Bitcoin ETF (HODL) from VanEck (the ticker is genuinely HODL).
- Ticker: HODL (Cboe BZX)
- Expense ratio: 0.20%
- AUM: $1+ billion
- Custodian: Gemini Custody
- Unique feature: 5% of profits to Bitcoin open-source development
HODL uses Gemini as custodian rather than Coinbase — diversity for investors concerned about Coinbase concentration risk. Also among the lowest-fee options.
Grayscale Bitcoin Trust (GBTC) — The Legacy Product
Grayscale Bitcoin Trust (GBTC) is the original institutional Bitcoin investment vehicle, converted to an ETF in 2024.
- Ticker: GBTC (NYSE Arca)
- Expense ratio: 1.50% — the highest of any major Bitcoin ETF
- AUM: $15+ billion (declining as assets flow to cheaper competitors)
- Custodian: Coinbase Custody
GBTC's high fee reflects its legacy as a trust that charged a premium for early institutional access. Now that cheaper alternatives exist, GBTC primarily serves investors locked in with embedded capital gains (selling triggers a taxable event; moving to IBIT requires selling).
New investors should not buy GBTC. Its only advantage is for existing holders with large unrealized gains who face a tax bill to switch.
Grayscale launched Grayscale Bitcoin Mini Trust (BTC) at 0.15% to compete on fees — but with less AUM and liquidity than IBIT or FBTC.
Franklin Bitcoin ETF (EZBC)
Franklin Bitcoin ETF (EZBC) from Franklin Templeton:
- Ticker: EZBC (Cboe BZX)
- Expense ratio: 0.19% (lowest among all major US ETFs)
- AUM: ~$500M
- Custodian: Coinbase + Bitgo
- Unique feature: 0.5% of revenue donated to Bitcoin open-source development
- On-chain recording: Holdings recorded on Stellar blockchain
EZBC is the cheapest Bitcoin ETF among established fund managers. Smaller AUM means slightly wider bid-ask spreads, but for long-term buy-and-hold investors, the lower fee is attractive.

International Bitcoin ETFs

Europe has a range of ETPs (Exchange-Traded Products, slightly different structure but same economic exposure):
- 21Shares Core Bitcoin ETP (CBTC) — major European player
- CoinShares Physical Bitcoin (CBTC) — UK/EU listed
- iShares Bitcoin ETP (Europe) — BlackRock's European product
- Invesco Physical Bitcoin ETP (BTIC) — Invesco European offering

Asia: Bosera HashKey Bitcoin ETF (3008.HK) and ChinaAMC Bitcoin ETF (3042.HK) trade on the Hong Kong Stock Exchange.
ETF vs. Buying Bitcoin Directly
For most individual investors, this is the most important decision:
| Factor | Bitcoin ETF | Direct Bitcoin |
|---|---|---|
| Custody | Fund manager | You (hardware wallet) |
| Annual fee | 0.15-0.25% | 0% |
| IRA/401k eligible | Yes | Limited |
| Self-sovereignty | No | Yes |
| Exchange risk | Low | Depends on custody |
| Tax reporting | 1099 (simple) | Complex (every trade) |
| Confiscation risk | Via fund/regulation | Only with your keys |
The fee matters at scale: 0.25%/year on $500,000 in Bitcoin = $1,250/year, compounding. Over 20 years, an ETF holder ends up with meaningfully less Bitcoin than a direct holder who simply buys and holds.
The sovereignty question: Bitcoin in an ETF is not your Bitcoin — it's a claim on Bitcoin held by a custodian. The ETF can be forced to sell (regulatory action), can have custody failures, and can be subject to AML/KYC restrictions that prevent redemption. For amounts you'd hold for decades, self-custody has real advantages.
Practical recommendation: Use ETFs for Bitcoin exposure in tax-advantaged accounts (IRA, 401k) where you can't self-custody. Use self-custody for your primary long-term holdings. See Bitcoin Cold Storage Guide.
Tax Considerations
Bitcoin ETFs are taxed like regular stock ETFs:
- Long-term capital gains (held >1 year): 0%, 15%, or 20% depending on income
- Short-term: Ordinary income rates
- In a Traditional IRA: Tax-deferred growth, ordinary income on withdrawal
- In a Roth IRA: Tax-free growth, no tax on qualified withdrawal
