BMNR vs BTBT: Which Is the Better Buy in 2026?

Last updated August 2026

Short answer

BMNR is the larger of the two ($10.42B market cap): the incumbent the market prices for continued execution (18.38x forward earnings, beta 1.67). BTBT is the smaller challenger ($462.95M): more room to run, but more to prove. The real question is which set of drivers you believe, and whether owning one (or both) leaves you over-concentrated.

Before you buy: how BMNR and BTBT affect your concentration

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. BMNR and BTBT share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined BMNR and BTBT exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

What does BitMine Immersion Technologies (BMNR) do?

BitMine Immersion Technologies (NYSE: BMNR) began as an immersion-cooling Bitcoin miner operating sites in Pecos, Texas and Trinidad, then executed a sweeping strategic pivot in mid-2025 under new chairman Tom Lee of Fundstrat. The company reoriented around an Ethereum-first treasury strategy, accumulating roughly 5.7 million ETH (worth on the order of $10 billion as of July 2026) and targeting ownership of about 5% of the total ETH supply. It stakes the bulk of that ETH through its proprietary MAVAN (Made in America Validator Network) platform to earn a staking yield of roughly 3%, and it has layered in DeFi strategies and venture-style equity stakes. BitMine has been added to the Russell 1000 and named to the Fortune Crypto 100.

What does Bit Digital (BTBT) do?

Bit Digital, Inc. (Nasdaq: BTBT) is a digital-asset and infrastructure company that has undergone a major strategic transformation. It started life as a bitcoin miner, but in 2025 it repositioned itself as what it calls a strategic-asset company centered on Ethereum. By mid-2026 it held roughly 155,000 to 160,000 ETH, making it one of the largest public corporate holders of Ethereum, and a large share of that stack is staked, either natively or through liquid-staking tokens, to generate ongoing yield. This makes the company's asset base and reported results move closely with the price of ETH and with staking economics rather than with a traditional product business.

BMNR vs BTBT: how do they differ?

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

  • BMNR drivers: Scale of the ETH treasury; Staking yield via MAVAN.
  • BTBT drivers: Ethereum treasury and staking yield; AI and HPC infrastructure via WhiteFiber.

Which fits which kind of investor

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: The dominant risk is Ethereum price itself: a sharp ETH drawdown would slash the value of the treasury and, because the equity carries a premium or discount, the stock can fall faster than ETH. For BTBT, the dominant risk is crypto price volatility: with the balance sheet dominated by Ethereum, a sharp ETH drawdown can slash the company's asset value and produce large mark-to-market losses, exactly the dynamic behind the sizable Q1 2026 net loss.

BMNR or BTBT: which should you pick?

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick BMNR if you believe its drivers more; BTBT if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the BMNR and BTBT guides.

BMNR vs BTBT: the full fundamentals

BMNR. BMNR is valued primarily off its crypto holdings rather than a conventional earnings multiple, and shares trade at a shifting premium or discount (mNAV) to the ETH and cash they represent. As of July 2026 the market cap (~$8.85 billion) sits near or below the stated crypto-plus-cash holdings, reflecting how much of the story is the underlying ETH. Reported net income swings with mark-to-market crypto values, so it is not comparable to recurring operating profit at a normal company.

BTBT. Bit Digital is best understood as a claim on assets (its ETH stack plus its WhiteFiber stake) more than as an earnings story, so conventional P/E and revenue multiples are of limited use. Reported net income is heavily distorted by non-cash mark-to-market accounting on crypto, meaning a big loss or gain in any quarter often reflects where Ethereum traded, not operating performance. Figures here are approximate and tied to the asOf date; verify live ETH holdings, staking levels, and financials before acting, because the company's strategy and balance sheet have changed rapidly.

Headline figures (approximate, JULY 2026): BMNR shows share price ~$15.55, market cap ~$8.85 billion, eth held ~5.7 million ETH (~4.8% of supply), total crypto + cash holdings ~$9.8 billion to ~$11 billion; BTBT shows business model Strategic-asset company: Ethereum treasury plus staking yield, plus AI/HPC infrastructure through a majority stake in WhiteFiber (WYFI), ethereum holdings Roughly 155,000 to 160,000 ETH in the first half of 2026, among the largest corporate ETH treasuries; a large share is staked, revenue Modest relative to the balance sheet (about $28 million in Q1 2026); reported results are dominated by crypto mark-to-market rather than steady operating income, profitability Reported a large net loss in Q1 2026, driven substantially by non-cash swings on crypto holdings; earnings can look very different quarter to quarter.

FAQ

What is the difference between BMNR and BTBT?

+

BitMine Immersion Technologies (NYSE: BMNR) began as an immersion-cooling Bitcoin miner operating sites in Pecos, Texas and Trinidad, then executed a sweeping strategic pivot in mid-2025 under new chairman Tom Lee of Fundstrat. Bit Digital, Inc. They show up together because they share investment themes, but they are different businesses, so the better fit depends on which thesis you are expressing.

Is BMNR or BTBT the better stock?

+

Neither is universally better. BMNR is the larger incumbent; BTBT is the smaller challenger. Walnut is informational, not investment advice. Compare what each does, the tie-breaker metrics above, and the risks, then decide which fits your thesis and what you already own.

Which is cheaper, BMNR or BTBT?

+

A lower multiple is not automatically the better buy: a richer valuation can be justified by faster growth, and a lower one can reflect real risk. Weigh the multiple against how fast each business is compounding.

Should you own both BMNR and BTBT?

+

Because they share themes, owning both concentrates you in that theme. That can be intentional (a focused bet) or accidental (less diversification than it looks). Walnut can show your combined exposure across both, and whether adding either over-concentrates you, before you buy.

What are the risks of BMNR vs BTBT?

+

BMNR: The dominant risk is Ethereum price itself: a sharp ETH drawdown would slash the value of the treasury and, because the equity carries a premium or discount, the stock can fall faster than ETH. The premium-to-NAV (mNAV) can compress from above 2x toward 1x or into a discount, hurting holders even if ETH is flat. Persistent equity issuance to buy more ETH dilutes existing shareholders. Staking, custody, and evolving crypto regulation add operational and legal uncertainty, and a short-seller report (Kerrisdale) has criticized the company for not routinely disclosing updated share counts, which complicates mNAV calculation. This is a speculative, high-volatility security, not a stable operating business. BTBT: The dominant risk is crypto price volatility: with the balance sheet dominated by Ethereum, a sharp ETH drawdown can slash the company's asset value and produce large mark-to-market losses, exactly the dynamic behind the sizable Q1 2026 net loss. Staking yield is not guaranteed and can fall with protocol changes, validator economics, or shifts in how much ETH is staked network-wide. The AI-infrastructure buildout through WhiteFiber is capital-intensive and unproven at scale, so it may require further financing, dilute shareholders, or fail to earn its cost of capital. The strategy also concentrates risk in a single crypto asset and depends on continued institutional acceptance of Ethereum treasuries. Regulatory uncertainty around digital assets, staking, and crypto-related securities adds another layer outside the company's control, and the stock's history of dilution and strategic pivots means past business models are a poor guide to the current one.
