FIDELITY WISE ORIGIN BITCOIN FUND (FBTC +3.89%) and iShares Ethereum Trust ETF (ETHA +5.92%) both offer pure-play crypto exposure at identical expense ratios, but differ in asset focus, risk profile, and scale.
Both FIDELITY WISE ORIGIN BITCOIN FUND (FBTC) and iShares Ethereum Trust ETF (ETHA) aim to provide investors with straightforward access to the price movements of a single cryptocurrency—bitcoin for FBTC, ether for ETHA—without the need to hold the digital assets directly. This comparison looks at cost, recent returns, risk, and what is inside to help investors decide which may better fit their portfolio objectives.

What's inside
ETHA delivers direct exposure to ether, with 100% of its portfolio allocated to Ether (ETH +6.28%) and no other assets or sector tilts. This single-asset focus means performance is entirely tethered to ether’s price, and the fund has been in operation for 1.6 years. Its top holdings are Ether (ETH +6.28%) 100.00% and USD Cash (CASH:USD) 0.00%.
FBTC, in contrast, tracks bitcoin nearly exclusively, holding 99.98% in Bitcoin (BTC +4.25%) and a negligible amount in Net Other Assets. Like ETHA, FBTC does not diversify across sectors or asset classes, but it is larger by assets under management and has a longer trading history. Both funds lack additional quirks or overlays and do not currently track a stated index.

What this means for investors
Bitcoin and Ethereum can trade like the same risk asset for stretches, but the resemblance breaks when the market starts pricing fundamentals instead of momentum. That is the real choice behind the Fidelity Wise Origin Bitcoin Fund and the iShares Ethereum Trust ETF . Both offer single-asset crypto exposure at the same fee, but they tie your portfolio to very different forces once the market stops moving in sync.
Fidelity Wise Origin Bitcoin Fund is a direct bet on Bitcoin’s price. There is no internal cushion and no secondary lever. If Bitcoin rallies, FBTC rallies. If Bitcoin sells off, FBTC takes the full hit. iShares Ethereum Trust ETF is also a single-asset vehicle, but Ether is tied more closely to what happens on the Ethereum network itself. That means ETHA carries an added layer of adoption and ecosystem dependence that can change how it behaves across crypto cycles.
For investors, FBTC fits those who want the cleanest possible exposure to a single asset with a clear narrative. ETHA fits those willing to accept added complexity in exchange for tying returns to a living network. Neither fund offers shelter in a sell-off, and both can draw down sharply when risk appetite fades. In strong crypto phases, bitcoin exposure often tracks broad momentum, while Ethereum exposure can diverge when network activity accelerates or stalls.
