BlackRock Just Announced a New Bitcoin ETF. Should You Buy it?

An interesting new asset linked to Bitcoin (BTC -1.06%) might make its debut soon. On Oct. 19, BlackRock (BLK +0.84%) submitted filings to the Securities and Exchange Commission (SEC) seeking permission to issue a new Bitcoin exchange-traded fund (ETF), the iShares Bitcoin Managed Protection ETF, ticker PBIT. Unlike the asset manager’s other Bitcoin ETF, the iShares Bitcoin Trust, the new one, if it’s approved, is intended to soften Bitcoin’s declines in exchange for capping its gains, according to the filing.

But how would that work, and would it make the new ETF worth buying if the SEC gives BlackRock the go-ahead?

This new asset is built around a central trade-off

Bitcoin is a great asset to own, but its main drawback, volatility, is more than many investors can stomach.

In its lifetime so far, the coin has experienced numerous declines of about 80%. Even when its pullbacks and bear markets are shallower than that, they can still be quite painful; it’s now 35% less than its all-time highs of $126,000, set about a year ago.

To address this problem, BlackRock’s new ETF would put a limit on those losses, like a seat belt that also puts a hard ceiling on the vehicle’s top speed.

Under the hood, the ETF would buy call options (rights to buy an asset at a set price, called the strike) on its main spot Bitcoin ETF, targeted at near 90% of its starting value. Then it would sell call options at higher strike prices to pay for the purchased calls. Each tranche’s initial loss exposure is thus about 10% before fees, while the sold calls cap the gains above their strike price.

Three overlapping tranches would be rolled monthly, so the downside insurance would be kept up to date at regular intervals, and each new tranche’s cap would reset higher or lower according to market conditions. After a rally, each new tranche’s buffer would start further below the current price.

This idea isn’t completely novel, and it has held up well in at least one recent test.

One ETF issued by Calamos targets full downside protection rather than a 10% buffer, and it lost just 1% of its value during its one-year protection period starting October 2025, while Bitcoin entered a bear market and plunged.

The catch is that the lost opportunity cost can be high during crypto bull markets, and even during regular seasonality.

Another Calamos 10%-buffer fund had a 22.2% upside cap for its one-year outcome period beginning Feb. 2, 2026. Across Bitcoin’s entire historical performance, it has grown by a median of 26.6% in the fourth quarter. For all of 2024, it gained 119.5%.

That would be a lot of upside to miss out on. The new ETF’s upside limits aren’t disclosed yet.

Should you buy the Managed Protection ETF instead of Bitcoin or Black Rock’s main Bitcoin ETF?

The Managed Protection ETF’s fee hasn’t been disclosed yet, either.

BlackRock’s spot Bitcoin ETF charges 0.25% per year. If that’s anything to go by, the additional features included with the Managed Protection ETF mean that its expense fee will likely be higher. Calamos’ 10%-buffer fund charges 0.69% per year.

In contrast, holding Bitcoin directly on an exchange or in a crypto wallet incurs no annual fee, though exchanges do charge transaction fees for each purchase and sale.

Taxes could be an issue, too. BlackRock’s prospectus states that its options strategy backing the ETF could generate short-term gains, which would then be taxed as ordinary income, thereby further damping the after-tax returns versus owning the asset directly.

So should you buy this new fund if the SEC says it can launch?

Probably not, unless you’re an investor who wants to own some Bitcoin but is fearful of panic-selling.

Even then, a small position or regular purchases in modest amounts may be easier to live with. By capping upside, the fund trims the short, vigorous rallies that drive much of Bitcoin’s return. And without that, there are better assets to own that don’t cost as much in fees.
