Bitcoin spot ETFs let you buy Bitcoin exposure through a normal brokerage account (Schwab, Fidelity, Robinhood) without needing a crypto wallet. For tax-advantaged accounts (IRA, 401k) or investors who don't want to manage private keys, they're the simplest Bitcoin investment.
Bitcoin spot ETFs launched in the US in January 2024 and fundamentally changed institutional Bitcoin access. By 2026, over $70 billion in assets under management across all Bitcoin ETFs — BlackRock's iShares Bitcoin Trust (IBIT) alone holds $45B+. This guide explains what they are, how they compare, and whether they're right for you.
How Bitcoin ETFs Work
A Bitcoin spot ETF holds actual Bitcoin in custody (not futures). When you buy one share of IBIT, you're buying a fractional claim on Bitcoin held by BlackRock's custodian (Coinbase Custody). You never hold the Bitcoin directly — no wallets, no private keys, no seed phrases. The ETF price tracks Bitcoin's spot price minus a small management fee. Ideal for: investors who want Bitcoin exposure in tax-advantaged accounts, retirees uncomfortable with self-custody, and investors using existing brokerage relationships.

|---|---|---|---|---|---|

IBIT vs FBTC — Key Difference
BlackRock IBIT uses Coinbase Custody for Bitcoin storage. Fidelity FBTC uses Fidelity's own proprietary custody solution — meaning Fidelity itself holds the Bitcoin. For institutional investors worried about Coinbase counterparty risk, FBTC's self-custody model is preferable. For individual investors, the difference is minimal — both are regulated, audited, and hold real Bitcoin. Expense ratios are identical at 0.25%.
"Bitcoin ETFs are the most successful ETF launch in history. IBIT crossed $10B in 60 days — faster than any ETF in history. The institutional demand was real and enormous." — Bloomberg ETF analyst Eric Balchunas
