Both the CoinShares Bitcoin Mining ETF (WGMI +4.71%) and iShares Ethereum Trust ETF (ETHA +0.14%) offer exposure to the crypto ecosystem, but they do so in fundamentally different ways: ETHA mirrors the price movement of Ethereum (ETH 0.56%) itself, while WGMI targets companies involved in Bitcoin mining and related infrastructure. This comparison breaks down the key differences to help investors understand which approach may appeal, depending on risk tolerance, cost sensitivity, and desired crypto exposure.
Snapshot (cost & size)
| Metric | ETHA | WGMI |
|---|---|---|
| Issuer | IShares | CoinShares |
| Expense ratio | 0.25% | 0.75% |
| 1-yr return (as of Jan. 24, 2026) | -9.94% | 92.48% |
| AUM | $10.14 billion | $355.66 million |
The 1-yr return represents total return over the trailing 12 months.
WGMI has a notably higher expense ratio than ETHA but has maintained positive yields, while ETHA’s price has declined over the last 12 months.
Performance & risk comparison
| Metric | ETHA | WGMI |

What's inside
WGMI currently invests in 25 companies, primarily in the technology sector. Its top holdings include IREN Ltd. (IREN +8.46%), Cipher Mining (CIFR +1.03%), and Hut 8 Corp. (HUT +5.62%) The fund has been trading for nearly four years and has increased in price by approximately 87.56% within that span.
ETHA, by contrast, is a single-asset trust that tracks the price of Ether, with 100% exposure to the cryptocurrency and no underlying equities. Less than two years old, the ETF’s price has fallen 15.62% since its inception.
What this means for investors
As with most cryptocurrencies, investors must be aware of the risks associated with crypto-related ETFs. ETHA especially carries a higher risk because it’s been on the market for less than 2 years and holds only Ethereum. So the fund’s price can be highly volatile and reliant on the coin’s success, as cryptocurrencies are generally more volatile than stocks.
And while WGMI’s holdings are actual stocks, many of its top holdings are tied to the crypto market, so it can carry a higher risk than many other ETFs.
It should also be noted that no beta measurement is provided for either ETF. The beta measures price volatility relative to the S&P 500, and is often calculated from five-year weekly returns. And since both funds are less than five years old, that type of measurement isn’t applicable at the moment.
Although neither ETFs offer dividends, WGMI has the edge over ETHA on price gains. However, WGMI may gradually become less of a Bitcoin mining ETF, as many mining companies, including those in the ETF, are actively transitioning to or incorporating high-performance computing (HPC) and AI data center operations.
Common reasons for transitions include diversifying revenue streams and/or moving away from mining, which has become increasingly controversial due to concerns about environmental impact. So if investors don’t mind the transition that WGMI is undergoing, it’s still a great option for indirect exposure to crypto.
