As of October 15, 2026, buying Bitcoin (BTC) through a spot ETF such as the iShares Bitcoin Trust (IBIT) or Fidelity's FBTC means a 0.25% annual fee, while holding BTC directly has no ongoing fee but puts custody on the holder. IBIT reported $65.74 billion in net assets on October 14, 2026.
Should you buy a Bitcoin ETF or hold Bitcoin directly?
The two routes buy the same asset exposure with different plumbing. The most recent dated example from our own coverage: US spot Bitcoin ETFs recorded a net outflow of $484.9 million on October 7, 2026, per Farside Investors, as covered in our post on the largest outflow since June 25. That figure counts shares sold by holders of the wrapper. A direct holder with coins in a personal wallet appears in no such daily figure, and their coins stay put until they move them.
The iShares IBIT page lists a 0.25% sponsor fee. On $10,000 that is $25 a year (derived from the stated rate, before any change in the Bitcoin price). Fidelity's FBTC also carries a 0.25% expense ratio, according to 247Wall St's September 28, 2026 comparison. The SEC's Investor.gov bulletin of September 9, 2024 explains the mechanism: the trust earns no income, so each fee payment reduces the bitcoin represented by each share.
Direct holders pay different costs. 247Wall St lists exchange trading fees, a network fee when moving coins to a personal wallet, and a hardware wallet at roughly $100 as a one-time cost.
| Item | Spot ETF (IBIT, FBTC) | Direct holding |
|---|---|---|
| Ongoing fee | 0.25% a year | None |
| Custody | Institutional custodian | Own keys or an exchange |
| Tax form | Form 1099-B | Form 1099-DA from exchanges |
| Retirement accounts | IRA, 401(k) if brokerage offered | Usually a crypto IRA provider |
Per 247Wall St, exchanges issue Form 1099-DA for direct sales, with cost basis reported only for coins bought after January 1, 2026, and personal wallet holders receive no tax reporting. ETF holders receive Form 1099-B showing proceeds and cost basis.
Where analysts disagree
The disagreement is mostly about which cost matters over a long holding period, and about which risk a holder would rather own.
The SEC bulletin frames the ETP as exposure without managing a wallet or keys, but warns that the share price can deviate from the Bitcoin price and that the sponsor fee erodes value over time. It is a regulator's risk list, not a recommendation.
PostFinance, a Swiss bank, argued in a bank comparison dated August 29, 2024 that spot ETFs have lower upfront costs but direct purchase has lower ongoing costs, and that ongoing costs matter more over time. Its sample on USD 10,000 showed a 10-year total of USD 1,042 for the ETF against USD 243 for direct purchase, with cost data as at June 30, 2024. Its text gives a different ETF figure, USD 1,379, which does not match its own table, so treat the table as the better-supported number. The comparison also reflects a Swiss investor facing currency and US tax issues, so it does not map directly onto a US buyer.
The Spark Team's comparison page is undated and describes its data as mid-2026. It says ETF costs typically exceed exchange fees within the first year for most funds, but also that ETFs suit short-term trades, retirement accounts and holders who do not want key management. 247Wall St adds that an ETF holder cannot withdraw coins to a personal wallet.
The readings differ on assumptions. A long holder who never trades favors direct holding on cost. A holder who values a retirement wrapper, tax statements and no key risk reads the 0.25% as the price of those features. Neither reading is wrong, and none of these sources claims otherwise.
Why it matters
Wrapper choice changes what the market can see. ETF flows are reported daily by Farside Investors and discussed in our post on whether ETF flows move price. On September 23, 2026, spot ETFs took in $346.9 million per Farside, yet Bitcoin fell as the 10-year Treasury yield rose, so a flow figure is one input, not the whole picture.
The scale of the wrapper is also visible in our coverage: our post on the $2.39 billion weekly inflow covered September 21 to 25, 2026, and our post on $707.9 million of outflows over three sessions covered the sessions ending October 9, 2026.
What to watch
- Farside Investors daily net flows for spot Bitcoin ETFs, published each trading day.
- IBIT's net assets and sponsor fee on the iShares product page, which carry an as-of date.
- Whether exchanges report cost basis on Form 1099-DA as described by 247Wall St for coins bought after January 1, 2026.
- Any change to sponsor fees in fund prospectuses.
Bottom line
- IBIT's sponsor fee is 0.25%, and FBTC's expense ratio is 0.25%, as of the sources cited on October 15, 2026.
- On $10,000, 0.25% is $25 a year (derived, before price changes).
- Direct holding has no ongoing fee but adds trading, network and wallet costs and key-loss risk.
- Sources disagree on which cost dominates, and one cited comparison contains an internal inconsistency.
