Grayscale Bitcoin Trust ETF GBTC charges 1.50% to hold bitcoin. Grayscale Ethereum Staking ETF ETHE charges 2.50% to hold ether. The same sponsor's mini funds, Grayscale Bitcoin Mini Trust ETF BTC and Grayscale Ethereum Mini Trust ETF ETH, charge 0.15% for the identical coins. Combined, $9.74 billion and $1.77 billion remain in the expensive share classes.

That fee gap is the live fact of the theme, not this morning's bounce. Bitcoin is at $80,231 as of 10:11 a.m. ET Friday, September 18, up 5.1% on the session. The iShares Bitcoin Trust ETF IBIT, which holds bitcoin, is up 5.0%. IBIT is still down 8.5% year to date and 30.9% over 12 months. An S&P 500 fund, SPY, is up 12.0% and 16.5% over those same windows. A Nasdaq-100 fund, QQQ, is up 17.0% and 22.1%. The wrapper put the coins in a brokerage account. It did not turn them into a quieter asset, and it did not empty those two share classes.

The menu got longer. The economic bet did not.

A 5% morning inside a 31% year

On Tuesday, September 15, the Senate failed to advance the Clarity Act, a bill that would have set out how US regulators oversee digital assets. US spot bitcoin funds posted $450 million in net outflows that session, the heaviest single day since June. IBIT closed down 3.6%.

The longer arc is less dramatic than a 5% print and more useful. IBIT is up 17.1% over one month and 27.5% over three months, a recovery that includes the August run in token funds we ranked here. It remains 36.8% below its 52-week high of $71.82. Bitcoin itself is 36.4% below its 52-week high of $126,198. Annualized volatility in IBIT is 49.2%, against 17.0% in SPY. The maximum drawdown in the bitcoin fund's history is 53.3%.

A morning like this one is what a 49% volatility asset does. It is not evidence that the drawdown is over.

These products are, with few exceptions, grantor trusts registered under the Securities Act of 1933. They hold the coin in custody and are designed to track its dollar price, minus expenses. They are not 1940 Act stock funds. They do not produce earnings. Where staking has been added, they can produce extra tokens. That is a different income mechanism, not a different directional bet.

Bitcoin is still the product

IBIT had $62.1 billion in assets as of Tuesday, September 15. It holds essentially 100% bitcoin, charges 0.25%, and turns over about $2.14 billion a day. That is the core of the theme: one coin, in size, with a creation-redemption process that has kept the share price close to the value of the bitcoin inside.

Assets under management, Sept. 15–18, 2026

IBIT holds more assets than the next ten combined

  • IBIT $62.1B
  • FBTC $13.9B
  • GBTC $9.7B
  • ETHA $9.1B
  • BTC $4.8B
  • BITB $2.9B
  • ARKB $2.7B
  • ETH $2.2B
  • ETHE $1.8B
  • FETH $1.4B
  • HODL $1.1B

Four ether funds make the list. Solana and XRP do not.

The next bitcoin funds do the same job at different prices. Fidelity Wise Origin Bitcoin Fund FBTC holds bitcoin, has $13.9 billion in assets, and also charges 0.25%. Bitwise Bitcoin ETF Trust BITB is $2.91 billion at 0.20%. ARK 21Shares Bitcoin ETF ARKB is $2.66 billion at 0.21%. VanEck Bitcoin ETF HODL is $1.13 billion at 0.20%. Franklin Bitcoin ETF EZBC is $424 million at 0.19%.

Then there is Grayscale's split screen. GBTC, the converted 2013 trust, still has $9.74 billion in assets and charges 1.50%. BTC, launched in July 2024, has $4.81 billion and charges 0.15%. Same issuer, same coin, 1.35 percentage points of fee between them.

Over the past 12 months that fee has shown up as a small gap in return, not a different trade. BTC is down 30.7%. IBIT is down 30.9%. FBTC and BITB are each down 30.9%. GBTC is down 31.7%. Among the 2024 bitcoin launches, the range is a fraction of a percentage point. The coin moved. The tickers followed. The selection variables that actually differ are the fee, the trading volume, and whether you are still paying the legacy Grayscale rate.

Assets for IBIT and ETHA are as of Tuesday, September 15; the other rows are as of Friday, September 18. Returns are total returns through this morning's session. Newer Solana and XRP funds do not yet have a one-year history.

The table's lesson is not which ticker "won." It is how little same-coin funds diverged, and how much the coin choice did.

Ether did the same thing, then added staking

ETHA had $9.10 billion in assets as of Tuesday, about one-seventh of IBIT. It holds ether, charges 0.25%, and has done what a pure-play is supposed to do: lose more than bitcoin has. It is down 13.9% year to date and 43.5% over 12 months. Fidelity Ethereum Fund FETH is $1.35 billion at the same 0.25% fee, down 13.8% and 43.5%. Vehicle choice did not rescue the year; the asset set it.

Staking is the construction difference that ether introduced. ETH holds ether, charges 0.15%, and appended the term staking to its name effective January 5, 2026. It paid $0.035 a share on September 3. It is down 12.9% year to date and 42.6% over 12 months, a modest gap versus ETHA that lines up with a lower fee and a small payout, not with a different market.

The expensive twin is still on the board. ETHE has $1.77 billion in assets and charges 2.50%, 2.35 percentage points above the mini fund. It is down 14.4% year to date and 43.9% over 12 months. Ether's 12-month volatility in ETHA is 70.5%, and the maximum drawdown is 67.9%. Paying 2.50% to own that path is a choice the mini share class exists to make unnecessary.

GBTC still holds twice the bitcoin of its 0.15% twin

  • GBTC / ETHE
  • BTC / ETH
  • Bitcoin
    • GBTC / ETHE $9.7B
    • BTC / ETH $4.8B
  • Ether
    • GBTC / ETHE $1.8B
    • BTC / ETH $2.2B

On ether, the mini has already overtaken the 2.50% class.

Solana and XRP lengthened the shelf

The 2025 launch wave is the part of the theme that did not exist when IBIT opened in January 2024. It is also still small.

Bitwise Solana Staking ETF BSOL is the scale product: $975 million in assets, 0.20%, and a mandate to hold Solana and stake it. US spot Solana funds have drawn about $1.37 billion in cumulative net inflows since they launched last October, $1.04 billion of that into BSOL. The fund is down 8.8% year to date, in line with the bitcoin funds on that window, and up 59.1% over three months and 8.4% this morning. That three-month burst is the same Solana run that led August's category ranking. It is not a one-year record. The fund does not have one yet. Inception was October 23, 2025.

REX-Osprey SOL + Staking ETF SSK is the construction exception, not a second Bitwise. It is active, charges 0.75%, and has $86.7 million in assets. Only 53.4% is Solana held directly. Another 42.6% is CoinShares Physical Staked Solana, with a smaller liquid-staking line behind that. Monthly distributions have been large enough that its year-to-date total return, -9.7%, beats its price return, -23.1%, by 13.5 percentage points. Fidelity Solana Fund FSOL, $195 million at 0.25%, shows the same staking gap in quieter form: -9.5% total return year to date against a -12.3% price return. That is income mechanics, not diversification. SSK is still a Solana bet, routed through extra wrappers.

XRP is the other new sleeve, and the most crowded. Bitwise XRP ETF XRP has $487 million in assets at 0.34%. Franklin XRP ETF XRPZ has $364 million at 0.19%. Canary XRP ETF XRPC holds XRP at a 0.50% fee. US spot XRP funds have drawn about $1.72 billion in cumulative net inflows since they launched. The two largest are down 25.7% and 25.4% year to date. XRP itself is at $1.36 this morning, up 5.3%, and 56% below its 52-week high of $3.10. A wider lineup did not produce a gentler asset.

Behind them sits a still-smaller tail of single-token trusts: Hyperliquid, Sui, Chainlink, Dogecoin, Avalanche. Grayscale Hyperliquid Staking ETF HYPG, which launched on June 3, has $181 million in assets at 0.29%. Those products add protocol-specific and classification risk on top of the same directional crypto cycle.

A basket is still mostly bitcoin

If the point of the new tickers is to own "crypto" rather than one coin, the index funds are the honest test. They do not pass it.

GDLC has $401 million in assets and charges 0.59%.

Holdings weights as of Sept. 18, 2026

The five-coin index is still a bitcoin fund

  • Bitcoin 74%
  • Ether 14%
  • BNB 4.7%
  • XRP 3.9%
  • SOL 2.8%

Ether, BNB, XRP, and Solana share the other quarter.

Bitwise 10 Crypto Index ETF BITW is larger, at $685 million, and more expensive, at 0.75%. It is 76.1% bitcoin and 14.6% ether, with XRP, Solana, and a scatter of smaller names in the residual. Hashdex Nasdaq Crypto Index US ETF NCIQ charges 0.25% and, on its latest holdings, is 74.5% bitcoin.

Call that a basket if you want. Economically it is a bitcoin fund with a drag from the coins that have done worse. GDLC is down 10.7% year to date and 32.1% over 12 months. BITW is down 10.7% and 34.2%. Both trailed IBIT. Breadth in the name did not mean breadth in the return.

That is the structural trap of market-cap crypto. Bitcoin is the largest asset, so a cap-weighted product keeps handing it the portfolio. You pay an extra fee, accept extra protocol risk in the remaining quarter, and still live with bitcoin's year.

The year, measured against what else you could have owned

Put the sleeves next to each other and the hierarchy is stable. Bitcoin funds are down about 8.5% year to date and 31% over 12 months. Ether funds are down about 14% and 43%. The largest XRP funds are down about 26% year to date. Solana, after a violent three-month bounce, is down 8.8% year to date in BSOL, in line with the bitcoin funds. Every one of those windows is worse than SPY and QQQ.

That comparison is not an argument that crypto should behave like equities. It is the opportunity cost of a satellite sleeve that has been this volatile. ETHA has seen a 67.9% maximum drawdown. IBIT's is 53.3%. XRPZ has already drawn down 56.9% in a life shorter than a year.

GBTC and ETHE still sit inside that drawdown at 1.50% and 2.50%. On today's $9.74 billion in GBTC, a 1.50% fee runs to about $146 million a year. The same bitcoin priced at the mini fund's 0.15% would cost about $15 million. The gap is $131 million a year. On $1.77 billion in ETHE, 2.50% runs to about $44 million a year against about $2.7 million at the mini rate.

Selling GBTC to buy a cheaper bitcoin fund is a taxable sale. The July 2024 mini-share distribution was the one Grayscale described as tax-neutral for holders. Two years later, $9.74 billion is still in the 1.50% class and $1.77 billion is still in the 2.50% class.

Frequently asked

Why do Grayscale's funds charge so much more than the mini versions?

The legacy trusts are the original converted products at 1.50% and 2.50%, while the mini funds hold the identical coins for 0.15%, and switching means a taxable sale.

Do the cheaper bitcoin funds actually perform better?

Only slightly: over 12 months the 2024 bitcoin launches landed within a fraction of a percentage point of each other, with the 1.50% legacy trust trailing by about a point.

Do Solana and XRP funds diversify a crypto sleeve?

No: they are separate directional bets on volatile single tokens, with the largest XRP funds down about 26% year to date and Solana's gain concentrated in one three-month run.

What about the multi-coin index funds?

They are roughly three-quarters bitcoin, cost more than a plain bitcoin fund, and trailed IBIT over both windows.

Does staking change what these funds are?

It adds an income mechanism that can make total return beat price return, in one Solana fund by 13.5 percentage points, but it does not change the directional bet.
