21Shares Crypto 10 ex-BTC ETF: A Bullish Way to Track Altcoins Without Bitcoin?

21Shares Crypto 10 ex-BTC ETF, trading under the ticker TXBC, gives investors regulated exposure to the top ten cryptocurrencies by market capitalisation with one deliberate exclusion: Bitcoin is left out entirely. 

Launched in the US market in late 2025, the fund sits within the growing category of crypto index products designed for those who want diversified altcoin exposure through a traditional fund structure without holding digital assets directly. 

Whether that exclusion makes TXBC a sharper tool or a limited one depends entirely on what an investor already holds.

Key Takeaways

• The 21Shares Crypto 10 ex-BTC ETF (TXBC) provides regulated exposure to a basket of the top ten cryptocurrencies by market cap, specifically excluding Bitcoin from the index at every rebalancing.
• The fund is designed for investors seeking diversified altcoin coverage across assets such as Ethereum, Solana, XRP, and others without the need to hold any cryptocurrency directly or manage a digital wallet.
• As with any narrowly focused fund, concentration in a specific asset class and the exclusion of Bitcoin carry a distinct risk and return profile that differs from broader crypto index products or single asset ETFs.

For investors who prefer to trade the underlying altcoins directly rather than through a fund wrapper, Bitrue provides a regulated exchange where you can access leading crypto assets in one place.

What is the 21Shares Crypto 10 ex-BTC ETF?

21Shares is a Europe based crypto exchange traded product issuer that has built a broad catalogue of single asset and index crypto products across global markets.

The company expanded into the US in 2025 with crypto index ETFs, with TXBC being one of the resulting products. 

The fund tracks an index of the top ten cryptocurrencies by market capitalisation, with Bitcoin specifically removed from the calculation. That single exclusion defines both the product's positioning and its intended audience.

The logic behind an ex BTC crypto fund is grounded in portfolio construction. Many institutional and experienced retail investors already hold Bitcoin through dedicated ETFs, direct ownership, or treasury allocations. 

Adding more Bitcoin through a broad index fund simply increases concentration in an asset they already have. 

A deliberate ex BTC index offers something structurally different: exposure to the tier of digital assets below Bitcoin, which often carry different momentum and volatility patterns, particularly during periods when altcoins move independently of Bitcoin's price direction.

The ETF structure matters here as much as the index methodology. Investors who buy shares in TXBC do not hold cryptocurrency directly. 

The fund holds the underlying assets on behalf of shareholders, removing the need for wallet management, private key security, or interaction with blockchain networks. 

For investors who want crypto exposure within a standard brokerage account and under a familiar regulatory framework, that accessibility represents a real practical advantage over direct ownership.

TXBC trades on a US exchange alongside conventional equity and fixed income ETFs, meaning it is reachable through existing brokerage relationships without opening a separate crypto account. 

That is a meaningful convenience for institutional allocators and retail investors working within regulated account structures where direct crypto custody is either restricted or operationally inconvenient.

What Does the TXBC Altcoin Basket Actually Hold?

The fund's methodology selects the top ten crypto index investing positions by market capitalisation, rebalancing periodically as rankings shift. 

Based on consistent market structure, Ethereum would occupy the largest weighting in the fund, given its long standing position as the second largest cryptocurrency by global market cap. 

Assets such as Solana, XRP, BNB, Dogecoin, Cardano, and others ranked within the broader top ten would form the remainder of the basket, with each asset's allocation proportional to its market cap relative to the group as a whole.

This composition produces a materially different risk profile from a Bitcoin-inclusive crypto index. Altcoins generally exhibit higher volatility than Bitcoin and can move substantially in both directions relative to it. 

In periods of positive sentiment across the broader crypto market, top altcoins have historically recorded larger percentage moves than Bitcoin on the upside. 

The reverse is equally true: during risk-off periods, Bitcoin-specific momentum runs, or broader market stress events, altcoin baskets tend to underperform a BTC-inclusive benchmark by a meaningful margin.

The market cap weighted approach also means the fund is not static. As market cap rankings change across crypto assets, the composition adjusts. An asset entering the top ten would be added; one falling below would be removed at the next rebalancing. 

This keeps TXBC representative of current market structure rather than locking in a historical snapshot that may diverge significantly from where capital is concentrated at any given point.

From a portfolio construction standpoint, TXBC addresses a gap that single asset ETFs cannot fill. Bitcoin ETFs provide BTC exposure; Ethereum ETFs provide ETH exposure. 

An altcoin basket covering the next tier of the market fills the middle ground for investors who want broader digital asset coverage without building and managing a multi-position crypto portfolio on their own.

How to Trade Crypto Altcoins on Bitrue

For investors who want exposure to the assets within an altcoin basket ETF framework but prefer direct trading over a fund structure, Bitrue provides a regulated exchange where the underlying crypto assets are accessible without management fees or the structural layers of an ETF wrapper. 

Whether you are building a position in Ethereum, Solana, XRP, or other assets that form part of a crypto index basket, Bitrue covers the trading side in a compliant and efficient environment. Here is how to get started:

1. Create an account and complete KYC: Register on Bitrue with your email address and complete identity verification to unlock full trading access.
2. Fund your account: Deposit USDT, USDC, or other supported assets into your Bitrue wallet, or purchase crypto directly through the platform.
3. Browse the markets: Search for Ethereum, Solana, XRP, or any other altcoin you want to trade across Bitrue's available market pairs.
4. Place a market or limit order: Choose your order type based on your approach. A market order fills immediately at the current price, while a limit order lets you set a specific entry point.
5. Consider self-custody: After building your position, consider withdrawing assets to a personal wallet for direct ownership and additional security over your holdings.

Bitrue gives you direct ownership of the underlying assets rather than shares in a fund, meaning your position reflects spot price movements without the operational layers of an ETF. 

For those who want to construct an altcoin portfolio on their own terms, it is a regulated and accessible starting point.

Conclusion

The 21Shares Crypto 10 ex-BTC ETF answers a specific and coherent question in portfolio construction: how does an investor add diversified altcoin exposure within a regulated fund structure without duplicating an existing Bitcoin position? 

TXBC provides one answer to that question, combining a market cap weighted altcoin basket with ETF accessibility and regulatory clarity. 

Whether the thesis suits a given investor depends on their portfolio composition, their view on altcoin versus Bitcoin performance, and their tolerance for the elevated volatility a concentrated altcoin basket carries. 

For those who prefer to trade the underlying assets directly, Bitrue offers a regulated and dependable platform to do exactly that without the fund structure.
