The Fidelity Wise Origin Bitcoin Fund (FBTC +0.34%) and the iShares Ethereum Trust ETF (ETHA 0.14%) both offer single-asset crypto exposure, but differ in underlying asset, recent performance, and drawdown severity.
The Fidelity Wise Origin Bitcoin Fund and iShares Ethereum Trust ETF give investors a way to access Bitcoin (BTC +0.07%) and Ether (ETH +0.21%), respectively, through traditional brokerage accounts. Both are designed for high-risk tolerance, with each ETF tracking just one cryptocurrency and exposing holders to the unique price swings of their underlying digital asset.

What's inside
iShares Ethereum Trust ETF is a pure play on Ether, with 100% of its portfolio in Ether and a negligible cash balance. The ETF, managed by iShares, has just one holding and is classified entirely within financial services. With $10.0 billion in assets under management (AUM) and a fund age of 1.5 years, it is a relatively new entrant focused exclusively on tracking Ether’s price movements.
The Fidelity Wise Origin Bitcoin Fund, on the other hand, is a bitcoin-only ETF, with 99.98% of assets in Bitcoin and a tiny fraction in other assets. Its sector breakdown is not reported, but the single-asset approach means price moves will closely follow Bitcoin itself. Neither ETF incorporates leverage, currency hedging, or other structural quirks.
What this means for investors
The iShares Ethereum Trust ETF and the Fidelity Wise Origin Bitcoin Fund are a way for everyday investors to gain exposure to specific crypto assets without exposing themselves to a cryptocurrency exchange. Several large cryptocurrency platforms that collapsed in recent years have made crypto-tracking ETFs popular options for individual investors.
The Fidelity Wise Origin Bitcoin Fund tracks the Fidelity Bitcoin Reference Rate. The iShares Ethereum Trust ETF measures itself against the Chicago Mercantile Exchange's CF Ether-Dollar Reference Rate.
Crypto ETFs free investors from having to manage a crypto wallet, but they don't free them from the volatility these assets are famous for. The iShares Ethereum Trust ETF is down by 39.5% from a peak it reached in August. This spring, it was down by more than half from the peak it set in late 2024. The Fidelity Wise Origin Bitcoin Fund has been less volatile, it's down by 30.3% from its previous peak. This is the third time it's fallen more than 25% since its inception in the first half of 2024.
