For Ethereum, iShares Ethereum Trust (ETHA) dominates with $7.8B AUM. Compare expense ratios, inflows, and your broker's availability before choosing. IBIT is best for low fees and liquidity, FBTC for Fidelity clients, and ARKB for Ark Invest followers.

As of Q2 2026, total Bitcoin ETF assets under management exceed $125 billion, with IBIT ($52B), FBTC ($18B), and GBTC ($16B) leading the pack [[1]][[11]]. Ethereum ETFs total ~$7.8B across ETHA, FETH, ETHE, and EZET. Daily inflows/outflows fluctuate based on Bitcoin price movement and institutional demand.

As of mid-2026, spot Solana ETFs are under SEC review with applications from VanEck, Grayscale, and 21Shares pending approval [[16]][[20]]. No spot Solana ETFs are currently trading, though futures-based products may be available. Analysts expect potential approval in late 2026 or early 2027. Monitor our tracker for real-time approval updates.

Spot ETFs hold actual cryptocurrency (Bitcoin or Ethereum), providing direct price exposure with minimal tracking error. All 11 Bitcoin and 4 Ethereum ETFs are spot products. Futures ETFs use Bitcoin futures contracts, which can have contango costs leading to performance drag over time. Spot ETFs are generally preferred for long-term investors due to lower costs and direct exposure.

ETF inflows occur when investors buy more ETF shares than they sell, requiring the issuer to purchase underlying crypto to back new shares. Outflows happen when more shares are redeemed than created, forcing the issuer to sell crypto. Sustained inflows indicate institutional confidence, while outflows may signal profit-taking or market stress. Our tracker monitors daily flows across all crypto ETFs.

Several spot Bitcoin ETFs offer the industry-standard 0.25% expense ratio: iShares Bitcoin Trust (IBIT), Fidelity Wise Origin Bitcoin Fund (FBTC), Bitwise Bitcoin ETF (BITB), and VanEck Bitcoin Trust (HODL) [[11]]. Grayscale's GBTC charges 1.50% due to its legacy trust structure, making it the most expensive option. For cost-conscious investors, IBIT, FBTC, or BITB are optimal choices.

Yes! Most major brokerages allow crypto ETFs in Roth IRAs, Traditional IRAs, and 401(k) plans. IBIT, FBTC, and GBTC are widely available across retirement accounts. This provides a tax-advantaged way to gain crypto exposure. Consult your broker for specific account eligibility and contribution limits.

Crypto ETFs offer several safety advantages: regulated by the SEC, insured custody through qualified custodians, no private key management required, and easier tax reporting. However, you don't own the underlying crypto and can't withdraw or use it. Direct ownership offers full control but requires secure storage. ETFs are generally considered safer for most investors [[26]].

The minimum investment is the price of one share. For IBIT (~$52/share), you can invest as little as $52. Many brokers offer fractional shares, allowing investments as small as $1. This makes crypto ETFs accessible to all investors, unlike direct Bitcoin purchases which may have higher minimums on some platforms.

Crypto ETFs are taxed like stock ETFs, not like direct cryptocurrency. Gains are subject to capital gains tax rates: short-term (held <1 year) taxed at ordinary income rates; long-term (held >1 year) taxed at 0%, 15%, or 20% depending on income. This is simpler than tracking individual crypto transactions for tax purposes.
