Plain English
A spot Bitcoin ETF (IBIT, FBTC, ARKB, etc.) holds actual BTC. A futures Bitcoin ETF (BITO) holds CME futures contracts and rolls them monthly. Spot ETFs track BTC price directly; futures ETFs typically underperform by 5–10% annually due to roll costs and basis decay.
How it actually works
Spot ETFs work via an authorized-participant creation/redemption mechanism: APs deliver BTC to the issuer in exchange for ETF shares, or vice versa. Futures ETFs hold front-month CME contracts; when each month expires, they sell expiring and buy further-out contracts. If the futures curve is in contango (further-out priced higher), each roll is a small loss.
What it means for you
For taxable HNW accounts (especially IRA/401k where direct crypto is not yet allowed), spot ETFs are now the cleanest way to hold BTC and ETH exposure. The cost: ETF expense ratio (~0.20–0.25%) plus an inability to self-custody. The benefit: tax-deferred holding, integration with traditional brokerage statements, easy estate handling. Futures ETFs are mostly obsolete now that spot ETFs exist.
