What Is the ProShares Bitcoin Strategy ETF (BITO)?

The ProShares Bitcoin Strategy ETF, ticker BITO, is the first U.S. Bitcoin-linked ETF.

It launched on October 18, 2021, and trades on the NYSE Arca exchange.

BITO does not hold actual Bitcoin.

Instead, the fund gains exposure to Bitcoin price movements through futures contracts — specifically, contracts traded on the Chicago Mercantile Exchange (CME).

The expense ratio for BITO is 0.95% annually, meaning an investor with $10,000 in the fund pays roughly $95 per year in management fees.

BITO is registered under the Investment Company Act of 1940, which places it under standard U.S. regulatory oversight — a layer of protection that direct crypto holdings do not provide.

How Does the ProShares Bitcoin Strategy ETF (BITO) Work?

A futures contract is an agreement to buy or sell an asset at a set price on a future date — without ever touching the asset itself.

BITO buys Bitcoin futures contracts on the CME, which lets the fund track Bitcoin's price without the fund ever holding a single BTC.

Here is the catch: those contracts expire each month.

When one contract approaches expiration, BITO sells it and buys a new, longer-dated contract — a process called "rolling."

When longer-dated contracts cost more than near-term ones — a condition known as contango — the rolling process creates a drag on returns.

This means BITO's performance can diverge from Bitcoin's actual spot price, especially over longer holding periods.

Investors should understand this structural difference before treating BITO as a one-to-one Bitcoin substitute.

ProShares Bitcoin ETF Lineup: BITO, BITU, BITI, and SBIT

ProShares offers four Bitcoin-linked ETFs, each built for a different type of market view.

BITO — ProShares Bitcoin Strategy ETF The original and largest in the lineup, BITO targets standard Bitcoin price exposure through futures contracts and may pay a monthly distribution.

BITU — ProShares Ultra Bitcoin ETF BITU targets 2x the daily performance of Bitcoin, using futures and swaps to amplify returns — and losses.

It is designed for short-term tactical trades, not long-term holding, because daily rebalancing causes returns to drift over time.

BITI — ProShares Short Bitcoin Strategy ETF BITI targets -1x the daily performance of Bitcoin, giving investors a way to profit when Bitcoin's price falls — all through a standard brokerage account, with no need to short the asset directly.

SBIT — ProShares UltraShort Bitcoin ETF SBIT targets -2x the daily performance of Bitcoin.

SBIT targets -2x the daily performance of Bitcoin and is intended for experienced investors who understand the compounding effects of leveraged inverse products.

ProShares Bitcoin ETF (BITO) vs. Spot Bitcoin ETFs: Key Differences

Once spot Bitcoin ETFs gained U.S. regulatory approval in January 2024, the conversation around BITO shifted.

Here is how the two structures compare.

What You Actually Own

BITO holds Bitcoin futures contracts — not Bitcoin itself.

Spot Bitcoin ETFs hold actual Bitcoin in custody, which means their price is designed to track the coin's real-time market value more directly than a futures-based structure.

Expense Ratio Gap

BITO carries a 0.95% annual expense ratio, reflecting the complexity and cost of managing a rolling futures portfolio.

Spot Bitcoin ETFs have generally carried lower annual expense ratios than BITO's 0.95%, reflecting the difference in operational complexity between holding physical Bitcoin and managing a rolling futures portfolio.

Contango Drag vs. Tracking Accuracy

Because BITO must roll futures contracts monthly, its returns can lag behind spot Bitcoin — particularly in markets where longer-dated contracts trade at a premium.

Spot Bitcoin ETFs do not face this rolling cost, so their tracking tends to stay tighter to the actual Bitcoin price over time.

Regulatory Structure and Custody Risk

BITO is registered under the Investment Company Act of 1940, which provides familiar investor protections and avoids the need for the fund to directly custody Bitcoin.

Spot Bitcoin ETFs hold the actual asset, which introduces a different risk profile around Bitcoin custody arrangements.

Neither structure eliminates the underlying volatility of Bitcoin itself — both rise and fall with the broader crypto market.
