Bitwise Bitcoin ETF (BITB) Review
BITB is Bitwise Asset Management's spot Bitcoin ETF — 0.20% fee, $5B AUM, and the only US issuer that publicly donates a portion of profits to Bitcoin open-source development.
TL;DR. Bitwise Bitcoin ETF (BITB) charges 0.20% (5 bp under IBIT, 1 bp under ARKB), uses Coinbase Custody Trust, and holds about $5B AUM. Bitwise is the only mainstream issuer that publicly commits to donating a portion of fund profits to Bitcoin Core open-source development. For investors who specifically want to support Bitcoin development through their ETF choice — or simply want a competitively-priced mid-tier alternative — BITB is the clearest fit.

Bitwise as an issuer
Bitwise Asset Management was founded in 2017 in San Francisco, specifically to build crypto investment products for the US market. Before the spot Bitcoin ETF approval, it had launched:
- The Bitwise 10 Crypto Index Fund (BITW) — a multi-asset crypto basket trading on OTC markets since 2017.
- Several private placement vehicles for institutional bitcoin and crypto exposure.
- A long-running Q4 crypto market outlook report widely cited in financial press.
The firm is smaller than BlackRock or Fidelity but has been operating in this space longer than either. Headed by Hunter Horsley (CEO) and Matt Hougan (CIO), Bitwise is one of the few US-native crypto-only asset managers with multi-year operating history.
The open-source funding commitment
BITB is the only US spot Bitcoin ETF that publicly commits to donating a portion of its fund profits to Bitcoin Core development. Specifically:
- 10% of profits earned from BITB are donated to organisations supporting open-source Bitcoin development.
- Disclosed recipients include Brink, OpenSats, and Chaincode Labs.
- Bitwise publishes a quarterly transparency report listing donation amounts and recipients.
From a pure-economics standpoint this doesn't affect the fund's expense ratio or your return — donations come from Bitwise's own corporate profits, not from fund NAV. From a values standpoint it's the differentiator BITB explicitly markets.
For investors who care about Bitcoin's open-source sustainability — a real concern given how few developers maintain the protocol — this is a clean way to channel fee revenue into protocol health.
Fees and tracking
BITB launched with a full 0% waiver until 11 July 2024 or the first $1B of AUM. The waiver expired (Bitwise crossed both thresholds quickly) and the headline 0.20% has applied since. The current fee is 5 bp below IBIT/FBTC, 1 bp below ARKB, and 1 bp above Franklin EZBC.
Tracking metrics:
- Average bid-ask spread (US hours): 3–4 basis points.
- 30-day average premium/discount to NAV: ±7 bp.
- One-year tracking error vs spot BTC (2024): within −24 bp.
Comparable to ARKB; slightly behind IBIT/FBTC by 2–3 bp on liquidity-sensitive metrics. Full fee context: expense ratios compared.
Custody
Coinbase Custody Trust — same as IBIT and most of the category. BITB inherits the same Coinbase concentration risk. The custody architecture and insurance are unchanged from the standard pattern covered in how Bitcoin ETF custody works.
The case for BITB
- Low fee. 0.20% — competitive with the cheapest mainstream options.
- Open-source mission. Unique selling point if you care about funding Bitcoin protocol development.
- Crypto-native operator. Bitwise has been in this space since 2017, longer than BlackRock or Fidelity.
- Transparent reporting. Quarterly published donation disclosures; clear product strategy.
The case against BITB
- Smaller AUM and volume. Liquidity is decent but a step below IBIT/FBTC/ARKB.
- Issuer concentration risk. Bitwise's revenue is heavily dependent on crypto products — smaller cushion in a multi-year crypto bear market than diversified BlackRock or Fidelity.
- Coinbase custody. No diversification from the dominant custodian.
Who should consider BITB
- Investors who want to support Bitcoin open-source development with their fund choice.
- Cost-conscious investors split between BITB (0.20%), EZBC (0.19%), and the Grayscale Mini (0.15%).
- Anyone wanting a credible non-BlackRock, non-Fidelity, non-Grayscale option.
FAQ
What is the expense ratio of Bitwise BITB?
0.20% per year. BITB launched with a 0% waiver for the first six months or $1B AUM, whichever came first; the waiver expired in mid-2024 and the headline 0.20% has applied since.
Does Bitwise really donate profits to Bitcoin development?
Yes. Bitwise publicly commits 10% of BITB profits to organisations supporting Bitcoin Core open-source development — including Brink, OpenSats, and Chaincode Labs. Quarterly transparency reports list amounts and recipients. Donations come from Bitwise corporate profits, not from fund NAV.
Who custodies the bitcoin held by BITB?
Coinbase Custody Trust Company — the same custodian used by IBIT, ARKB, EZBC and most of the US spot Bitcoin ETF category. The bitcoin is held in segregated cold-storage addresses under multi-signature key schemes.
How does BITB compare to IBIT?
BITB charges 0.20% vs IBIT's 0.25% (a 5 bp saving on a $100k position = $50/year). BITB is roughly 1/14 the AUM with thinner liquidity. The structural differentiator is BITB's open-source donation commitment, which IBIT does not offer.
Is Bitwise a reliable ETF issuer?
Bitwise has been operating crypto investment products since 2017 — longer than any of the larger ETF issuers it now competes with. The firm has multi-year compliance, custody and operational track record specifically in crypto. Smaller balance sheet than BlackRock or Fidelity but a focused, established operator.
