Bitmine Buys 10.4K ETH, Now Holds ~4.8% of Supply, Stakes 85%

TL;DR: Bitmine Immersion Technologies (BMNR) doubled down on Ethereum accumulation, adding 10,399 ETH to bring its treasury to 5,797,813 ETH (roughly 4.8% of circulating supply) while repurchasing 4.5 million shares. Despite the buys and continued staking of a large portion of its holdings, the stock slipped toward $17 as investors weighed massive unrealized losses and ongoing market risks. Bitmine’s buy wave continues Bitmine reported another purchase of 10,399 ETH over the past week, following a 9,946‑ETH buy the week prior. Those two transactions pushed more than 20,000 ETH into the company’s treasury in roughly a fortnight, growing its total to 5,797,813 ETH — approximately 4.8% of Ethereum’s circulating supply. Staking strategy and paper losses The miner has staked the bulk of its position: 4,917,189 ETH, or about 85% of its holdings. At the stated valuation, the staked ETH is worth roughly $9.2 billion and Bitmine estimates annualized staking revenue near $247 million. Despite the yield potential, DropsTab estimates Bitmine is carrying roughly $8.8 billion in unrealized losses on its Ethereum position — a reminder that staking income does not eliminate mark-to-market exposure. Why Bitmine is doubling down Chairman Tom Lee linked the buybacks to ETH’s recent relative strength. He noted ETH outperformed the Nasdaq‑100 by about 25% in July — the widest margin since July 2025 — and pointed to sharp rallies in ETH last year (from ~$2,375 in July 2025 to $4,057 the following month). Lee framed the accumulation as a bet on crypto fundamentals, but he and the company also noted past performance doesn’t guarantee future returns. Share buybacks and capital strategy On top of accumulating ETH, Bitmine repurchased 4.5 million common shares last week — its third consecutive week of buybacks and bringing total repurchases to more than 16 million shares. Management said it views BMNR as attractively valued relative to its assets and long‑term ETH strategy. Share repurchases can support per‑share metrics, but their impact depends on purchase price, funding sources and whether any future issuance offsets the reduction. Risks to investors BMNR gives U.S. investors equity exposure to Ethereum without direct token custody, but it carries corporate risks that a spot ETH ETF would not: management decisions, financing, dilution and operational risks tied to running staking infrastructure. The company’s large ETH cost basis, market volatility, validator performance and changing staking yields all affect the economics and risk profile. Market reaction and technical picture Investors were muted: BMNR traded near $17.06 on August 3, down about 1.3% on the day (intraday range $16.63–$17.23). Technical indicators show the stock testing the 61.8% Fibonacci retracement at $17.15 as immediate resistance; a daily close above that could open a move toward $18.49 (50% retracement), then $19.82 and $21.48 if momentum improves. The stock remains above an ascending trendline from its June low (~$12.81), suggesting the short‑term recovery isn’t broken, but an ADX below 20 points to a weak prevailing trend. Failure at $17.15 could push BMNR back toward the rising trendline near $16, with stronger support at the 78.6% retracement ($15.24); a decisive break would raise the odds of retesting $12.81. Bottom line Bitmine is maintaining an aggressive ETH accumulation and staking posture while simultaneously buying back shares — a strategy that amplifies both upside if ETH and the business rebound, and downside if prices or staking economics deteriorate. Investors should weigh the company’s large paper losses, concentrated exposure to ETH and the unique risks of staking versus direct token ownership.
