Abstract

Since the historic approval of the Bitcoin spot ETF by the US Securities and Exchange Commission (SEC) in January 2024, the cryptocurrency investment sector in the United States has significantly matured. By 2026, investors can participate in the cryptocurrency market through four main channels: spot ETFs, crypto equity companies (mining enterprises and treasury companies), leveraged and inverse ETFs, and blockchain-themed funds. As of March 30, 2026, US Bitcoin spot ETFs collectively held approximately 1.29 million BTC, with a total scale of about $86.9 billion; the Ethereum spot ETF had a scale of about $18 billion. Notably, the rise of the Ethereum treasury company model is reshaping the logic of institutional participation—represented by Bitmine Immersion Technologies (BMNR), which generates native income annually through staking, forming a business resilience distinctly different from Bitcoin treasuries. From a regulatory perspective, the 2025 GENIUS Act established the first federal stablecoin framework, officially establishing the US strategic Bitcoin reserve, allowing banks to conduct crypto custody, and completely breaking compliance bottlenecks. However, the high volatility of leveraged ETFs, debt risks of treasury companies, and staking asset slashing risks still pose significant investment obstacles. For investors seeking to allocate in this sector, constructing a layered portfolio that includes core positions, industry beta, and high-risk exposure may be the most feasible participation path.

1. Definition and Evolution Logic

The US stock cryptocurrency sector is essentially a type of investment that allows trading of cryptocurrency-related assets in the form of stocks on traditional stock exchanges. Investors do not need to directly hold cryptocurrency private keys to participate in this high-growth sector through familiar securities accounts. The evolution of this model reflects the complete journey of crypto assets from the "geek circle" to "mainstream institutions."

From the perspective of evolutionary stages, the growth of this sector has gone through three key phases. The first phase is the "underground mining period" (2017-2020), represented by pure mining companies such as Riot Blockchain and MARA Purpose, characterized by a single business model, chaotic governance, and vague valuation logic, primarily trading in the pink sheets market with extremely poor liquidity, and mainstream institutions hardly paying attention to such assets. The cryptocurrency stocks during this period were highly bound to the cryptocurrencies themselves, with volatility far exceeding that of the underlying assets, referred to by the market as "leveraged Bitcoin."

The second phase is the "compliance securitization period" (2021-2023), marked by the direct listing of Coinbase (NASDAQ: COIN) and MicroStrategy's (NASDAQ: MSTR) large-scale Bitcoin accumulation plan. The emergence of compliant exchanges signifies the industry's move towards normalization, with Coinbase being the only publicly listed cryptocurrency exchange in the US, and its direct listing on NASDAQ in April 2021 being of milestone significance. Meanwhile, MicroStrategy accumulated over 150,000 Bitcoins between 2020-2023, rebranding itself as a "Bitcoin Treasury Company," pioneering a new paradigm of corporate valuation.

The third phase is the "explosive growth of ETF products" (2024 to present), marked by the SEC's approval of the Bitcoin spot ETF, formally integrating crypto assets into mainstream US financial products. The BlackRock iShares Bitcoin Trust (IBIT) accumulated several tens of billions of dollars in assets within months post-listing, becoming the fastest-growing ETF category in history. The core feature of this phase is productization—the risk-return characteristics of cryptocurrencies have been encapsulated as standardized financial products, lowering the compliance thresholds for institutional entry and enabling retail investors to achieve professional-level exposure management at a lower cost.

2. Market Structure and Competitive Landscape

From a market structure perspective, the US stock cryptocurrency sector in 2026 presents a "triple pole" product landscape: spot ETFs dominating, crypto equity companies providing beta exposure, and leveraged and themed products meeting precision demands.

In the spot ETF domain, the market is highly concentrated, with Bitcoin ETFs collectively holding approximately 1.32 million BTC, currently totaling about $107.3 billion. The BlackRock iShares Bitcoin Trust (IBIT) occupies about 60% market share with approximately $55 billion in assets, and its 0.25% management fee is distinctly competitive among similar products. Fidelity Bitcoin Trust (FBTC) has a size of about $13 billion, also adopting a 0.25% fee rate, making it IBIT's most direct competitor. Grayscale's GBTC was once the largest cryptocurrency trust fund but faces high pressure with a 1.50% fee after transitioning to an ETF, currently scaled at about $10 billion; meanwhile, the BTC mini-trust with a fee rate of only 0.15% (approximately $3.5 billion) diverts funds sensitive to low fees. Regarding new entrants, Morgan Stanley's MSBT officially listed in April 2026, marking a traditional banking giant's entry into the crypto ETF space, signaling significant industry implications.

For Ethereum ETFs, BlackRock's ETHA (about $7.1 billion) leads the pack, also being the largest single Ethereum ETF product at present. Notably, BlackRock's ETHB launched in 2026 supports staking yields for the first time, pioneering the acquisition of native crypto yields through ETFs, which may reshape ETF product design logic. After regulatory reform in 2025, altcoin ETFs officially opened up, attracting about $1 billion each for XRP and Solana categories; it is expected that by 2026, more than 26 new emerging altcoin ETFs (such as Dogecoin, Chainlink, etc.) will be launched, transitioning the crypto ETF product line from the BTC/ETH duopoly era to a "one strong and many powerful" multi-category era.

In the crypto treasury and mining company sector, the landscape is undergoing structural differentiation. MicroStrategy (MSTR), as the pioneer of the Bitcoin treasury model, currently holds approximately 700,000 Bitcoins, making it the publicly listed company with the largest Bitcoin holdings globally. However, with the Bitcoin price having decreased by around 18% since early 2026 to near some companies' holding costs, the accumulation behavior of pure mining companies such as MARA and RIOT has significantly slowed, raising questions about the sustainability of the treasury model. Unlike Bitcoin treasury companies facing the common dilemma of "forced selling," emerging Ethereum treasury companies represented by Bitmine Immersion Technologies (BMNR) showcase a distinct business logic. BMNR generates approximately $196 million in recurring staking income annually through its MAVAN staking infrastructure, enabling the company to cover operational expenses without selling crypto assets, forming a true "native blood generation function." As of 2026, BMNR holds approximately 4.8 million ETH, with a market value of about $10.8 billion, accounting for 3.98% of the global ETH supply, aiming to hold 5% of the global ETH supply. Once achieved, this scale will make BMNR a significant holder in the Ethereum ecosystem.

In terms of leveraged, inverse, and thematic ETFs, the risk-return profiles of products exhibit significant differences, requiring cautious discernment from investors. Leveraged ETFs amplify daily returns through derivatives; by the end of 2025, the 2x leveraged MicroStrategy MSTX and MSTU plummeted by about 80%, resulting in approximately $1.5 billion in evaporated retail assets, revealing the extreme risks of this product type. Mainstream products include BITO (1x BTC futures), ETHU (2x ETH futures), and MSTZ (inverse MSTR), among others. Blockchain-themed funds provide indirect exposure for conservative investors—BKCH (Global X) heavily invests in Coinbase and core mining companies, BLOK (Amplify) covers around 80 blockchain-related stocks, and STCE (Charles Schwab) has a fee rate of only 0.30%, encompassing about 40 stocks such as MicroStrategy and Bitdeer, making it suitable as a core tool for long-term allocation.

3. Core Risk Analysis

The high-growth characteristics of the US stock cryptocurrency sector are accompanied by a complex and diverse risk dimension. Before constructing an allocation portfolio, investors need to establish a clear understanding of the following four layers of risk.

The first layer of risk is the dynamic uncertainty of the regulatory framework. Although the 2025 GENIUS Act established the first federal stablecoin framework and officially established the US strategic Bitcoin reserve, allowing banks to conduct crypto custody, the overall regulatory framework for cryptocurrencies is still evolving. The delineation of jurisdiction over crypto assets between the SEC and CFTC has not yet fully clarified, and there may still be frictional space in the approval pace of some altcoin ETFs. Furthermore, if the Trump administration adjusts financial regulatory directions in 2026, the continuity of related policies may face certain uncertainties regarding whether regulatory dividends can be sustained.

The second layer of risk is the high volatility of underlying assets. The cryptocurrency market is known for extreme volatility, evidenced by the approximately 18% decline in BTC from early 2026 to present. This volatility transmits to investor levels through ETFs and stock products, and due to friction costs such as management fees, holding discounts, and liquidity premiums in some products, actual losses often exceed the direct decline of the underlying asset. For investors allocating this sector in their portfolio, it should be viewed as a high-risk asset, with strict control over position ratio to avoid the tail risks arising from excessive concentration in a single asset.

The third layer of risk lies in the financial structure risks of crypto treasury companies. Taking MicroStrategy as an example, the core logic of its treasury model is to finance by issuing convertible bonds and preferred stock to buy Bitcoin, expecting the price increase of Bitcoin to exceed financing costs. However, this model carries significant financial leverage—if Bitcoin continues to decline, the value of Bitcoin holdings not only shrinks, but the interest expenditures and repayment pressures on the funding side will also amplify simultaneously. Although BMNR's staking revenue model is more resilient, the staking yield itself fluctuates with Ethereum prices and faces potential slashing risks, where holdings of ETH may be deducted if validating nodes exhibit malicious behavior. Investors allocating such assets need to pay attention to both the company's financial structure and the cyclical risks of the underlying crypto assets.

The fourth layer of risk is the liquidity and tracking errors at the product level. For leveraged ETFs and some smaller crypto stocks, extreme intraday fluctuations may lead to liquidity exhaustion, widening spreads, and increasing trading costs. More importantly, the "compounding decay" mechanism of leveraged ETFs means that even when the directional judgment is correct, long-term holding of leveraged ETFs may incur accumulated losses due to daily rebalancing—lessons from MSTX/MSTU at the end of 2025 profoundly illustrate this point. Furthermore, although the historical discount of Grayscale's GBTC has narrowed after its transition to an ETF, its relatively high management fee rates and lack of yield support still greatly diminish its attractiveness to institutional funds compared to competitors like IBIT.

4. Innovation Trends and Sector Opportunities

Despite numerous risks, the US stock cryptocurrency sector in 2026 demonstrates several noteworthy new trends that are reshaping the investment logic and product landscape of the sector.

The first trend is the emergence of "staking ETFs," which represent the most groundbreaking product innovation of 2026. BlackRock's ETHB supporting staking yields means that ETF holders can indirectly obtain staking yields from the Ethereum network without needing to run validating nodes or stake through DeFi protocols. This innovation upgrades ETFs from passive holding tools to active income generators, significantly expanding the product's application scenarios. For institutional investors, ETHB offers a compliant, convenient way to earn ETH income without needing to hold private keys, a demand that was nearly unmet in the traditional financial system. If ETHB gains market acceptance, it can be expected that more staking ETFs based on other PoS chains will emerge, further broadening the product boundaries of the ETF industry.

The second trend is the rise of specialized Ethereum treasury company models. In contrast to Bitcoin treasury companies' "buy and wait" model, Ethereum treasury companies generate native income through staking, forming a commercial closed loop—even if the crypto market enters a bear phase, staking returns can still cover operational expenditures, allowing the companies to avoid forced sales of holdings. BMNR aims to hold 5% of global ETH supply as its strategic goal, and if this is achieved, it will become a systematically influential holder in the Ethereum ecosystem, whose strategic decisions (such as whether to participate in PoS governance, adjustments of staking parameters, etc.) will have substantial impacts on the entire network. This model may give rise to more specialized ETH treasury companies, forming a brand-new investment sub-sector.

The third trend is the structural inflow of institutional funds and the rise of on-chain fixed-income assets. Data shows that even with Bitcoin's approximate 18% decline from early 2026 to present, institutional funds are migrating towards on-chain fixed-income assets. This trend closely correlates with the maturity of the Ethereum staking ecosystem—projects like EigenLayer and Pendle Finance have built re-staking and yield tokenization infrastructures, allowing staking yields to be structured, fragmented, or even used as collateral in the DeFi ecosystem. Ethereum treasury companies like BMNR, generating stable returns through MAVAN staking, perfectly align with institutional investors' strong demand for "crypto native income without price risk exposure."

The fourth trend is the continuous expansion and multi-chain diversification of ETF product lines. From the BTC/ETH duo to the launch of ETFs for mainstream altcoins like XRP/SOL, to expectations of new emerging targets like Dogecoin and Chainlink approved in 2026, ETF products are undergoing a refined upgrade from "mainstream coin coverage" to "precision sector allocation." The oracle infrastructure of Chainlink, the high-performance public chain positioning of Solana, and the MEME cultural attributes of Dogecoin correspond to different investment themes such as DeFi, infrastructure, and community culture; multi-chain diversification of ETF products will enable investors to express their judgments about specific sectors more precisely, rather than passively holding the entire crypto market.

5. Participation Strategies and Investment Logic

For investors wishing to allocate in the US stock cryptocurrency sector, the following provides a reference framework based on risk layering for investors to make judgments in accordance with their own situations.

From the core position perspective, BTC and ETH spot ETFs (especially the low-fee IBIT and ETHA) are the most universal participation tools. Considering the existing scales of about $86.9 billion for BTC spot ETFs and about $18 billion for ETH ETFs, together with the endorsement of BlackRock, the world's largest asset management company, these two types of products possess sufficient liquidity, low tracking error, and clear regulatory compliance. It is recommended to allocate them as "industry beta" in the portfolio, controlling position ratios in the range of 1% to 5%, primarily undertaking exposure to the overall trend of the crypto market.

From the industry beta perspective, blockchain-themed funds (such as BKCH and BLOK) provide diversified exposure covering exchanges, mining operators, and infrastructure stocks. Compared to directly holding single crypto companies, thematic funds can mitigate the impact of black swan events on individual stocks while sharing the systemic dividends of the entire crypto ecosystem's growth. For risk-averse investors, this may be the most suitable entry point. STCE, with a relatively low fee of 0.30%, is suitable as a long-term core allocation.

From a high-risk high-return perspective, Ethereum treasury company BMNR and Bitcoin treasury company MSTR are suitable for investors willing to tolerate higher volatility in exchange for potential excess returns. BMNR's staking yield model provides operational resilience compared to MSTR, while MSTR's "aggressive accumulation + leveraged buying" strategy demonstrates strong elasticity during bull markets. It is advisable to control the positions of such assets within 0.5% to 2%, while continuously tracking the company's financial structure changes and the impact of crypto asset price trends on repayment capabilities.

From a tactical allocation perspective, leveraged and inverse ETFs (such as MSTX and MSTZ) are only suitable for professional investors with timing abilities for the short term, and holding periods should be measured in days or weeks, strictly prohibiting long-term holding. The compounding decay mechanism of leveraged ETFs means that even with correct directional judgment, long-term returns may fall far below the price movements of the underlying asset. For most ordinary investors, this category should be approached with restraint.

It is particularly emphasized that the above analysis is for reference only and does not constitute any investment advice. Crypto assets carry extremely high volatility and uncertainty, and investors should make prudent decisions after fully assessing their risk tolerance. Leveraged products pose compounding decay risks, and staking assets face slashing risks, while crypto treasury companies experience financial leverage pressures—no single asset should be held at excessively high proportions, and maintaining portfolio diversification is key to long-term survival.

6. Conclusion and Outlook

Based on the above analysis, the US stock cryptocurrency sector is at a critical stage of transition from the "product innovation phase" to the "ecosystem maturity phase" in 2026. The Bitcoin spot ETF has opened the door for institutional entry, while the Ethereum staking ETF and Ethereum treasury companies are redefining the business model of "compliant holding of crypto assets." The regulatory framework established by the 2025 GENIUS Act provides unprecedented policy certainty for the industry; banks being permitted to conduct crypto custody and the establishment of a federal stablecoin framework mean that the status of crypto assets in the US financial system is now irreversible.

Looking forward, several key observation indicators are worth continued tracking. First, whether the scale of staking yields from Ethereum treasury companies can continue to expand will determine the long-term viability of this business model; second, the inflow of funds into the staking ETF (ETHB) will verify the market acceptance of the product innovation of "ETF + native yields"; third, the actual approval pace and initial fundraising scale of altcoin ETFs like XRP and Solana will reveal the commercialization space beyond mainstream coins; fourth, further clarification of the US regulatory framework at the federal level will determine whether the long-standing institutional dividends in this sector can continue.
