This page focuses on US-listed spot Bitcoin ETFs (IBIT, FBTC) and US brokerage accounts. In other countries, similar ETF products may exist but the tickers and tax treatment differ.
THE SHORT VERSION
A Bitcoin ETF gives you price exposure with zero custody complexity. Real Bitcoin gives you sovereignty, no counterparty, no custodian, full control. For a 401(k) or IRA where self-custody isn't possible, an ETF is a reasonable option. For meaningful long-term holdings outside retirement accounts, self-custody is the standard.
What a Bitcoin ETF is
A spot Bitcoin ETF is a fund that holds actual Bitcoin on behalf of shareholders. You buy shares of the fund, not Bitcoin directly. The fund's share price tracks the Bitcoin spot price.

- IBIT (iShares Bitcoin Trust, BlackRock)
- FBTC (Fidelity Wise Origin Bitcoin Fund)
- Plus ARKB (ARK/21Shares), BITB (Bitwise), HODL (VanEck), and others
What you get with an ETF
- Price exposure to Bitcoin.
- Eligible for retirement accounts. You can hold IBIT or FBTC inside your Roth IRA or 401(k) if the plan allows it.
- No seed phrase to manage.
- No hardware wallet required.
- Taxed as a security with standard brokerage reporting.
- Liquid during market hours. Buy and sell like any stock.
What you give up with an ETF
- No self-custody. BlackRock (IBIT) or Fidelity (FBTC) custodies the Bitcoin on your behalf. You hold shares of the fund, not keys to the Bitcoin.
- No Lightning Network access.
- No ability to spend or receive Bitcoin directly.
- Exposure to ETF-level counterparty risk. BlackRock failing is a different risk from FTX failing, but it is not zero.
- Annual expense ratio. IBIT is 0.25 percent, FBTC is 0.25 percent verify×DON'T TRUST, VERIFYClaim: IBIT and FBTC each carry roughly 0.25 percent annual expense ratios.Verify at: IBIT product page ↗ · FBTC fact sheet ↗Expense ratios may change. Check current fund documents before relying on these figures..
- Cannot withdraw Bitcoin. You can only sell for cash. There is no in-kind redemption for retail holders.
What you get (and give up) with self-custody
SELF-CUSTODY GAINS
- True ownership, no counterparty.
- Can transact. Spend, receive, use Lightning.
- Cannot be frozen by any company.
- No annual fee.
SELF-CUSTODY TRADEOFFS
- Responsibility for security. Lose the seed phrase, lose the Bitcoin.
- Cannot hold directly in a 401(k) or IRA. A self-directed IRA with a specialized custodian exists but is complex.
- More steps to buy and manage.
The honest recommendation
FOR RETIREMENT ACCOUNTS
When self-custody isn't practical (401(k), IRA), IBIT or FBTC is the right option. Either one. Don't let "it's not real Bitcoin" purism cost you tax-advantaged compounding.
FOR MEANINGFUL HOLDINGS OUTSIDE RETIREMENT ACCOUNTS
Self-custody with a hardware wallet. Past roughly $1,000 in value, the cost of a hardware wallet is justified by eliminating counterparty risk entirely. See Hardware Wallets.
The two approaches are not mutually exclusive. Many people hold IBIT in their Roth IRA and self-custodied Bitcoin in a hardware wallet.
A note on Robinhood
Robinhood Crypto did not originally permit withdrawing Bitcoin to an external wallet. That changed. Robinhood rolled out crypto withdrawals to external wallets starting in 2022, with broader availability in 2023 verify×DON'T TRUST, VERIFYClaim: Robinhood Crypto supports withdrawing Bitcoin to external self-custody wallets.Verify at: Robinhood support: crypto wallets ↗Robinhood's own support documentation describes the wallet feature. Availability and limits can vary by state and account status; confirm before transferring significant amounts..
So the old claim "you can't withdraw Bitcoin from Robinhood" is out of date. The more accurate concerns today are:
- Default is custodial. Until you withdraw, Robinhood holds your keys. Same counterparty-risk profile as any other crypto exchange.
- Trust history. Robinhood halted trading of GameStop and other stocks in January 2021 during high volatility. That event made many users question whether they want a broker that has demonstrated it will restrict buying or selling under pressure.
- Broker-first UX. No Lightning support. No detailed UTXO management. If you want to actually use Bitcoin (not just hold price exposure), a Bitcoin-focused exchange is a better fit.
For real Bitcoin with a clean self-custody workflow: use River, Swan, or Strike and withdraw to a hardware wallet. See How to Buy Bitcoin.
