Bitmine acquires more than $230 million in ether (ETH) its largest weekly haul of 2026

BitMine Immersion Technologies (BMNR), the largest Ethereum-focused digital asset treasury firm, sped up its crypto purchase pace as chairman Tom Lee sees growing signs of the crypto “mini-winter” ending.

The firm reported Monday it acquired 101,627 ether (ETH) last week, its largest weekly haul since December 15. The purchase, worth roughly over $230 million at current ETH prices, lifted BitMine’s total holdings to 4.97 million ETH.

The move comes as most digital asset treasuries — except Michael Saylor’s bitcoin-focused Strategy (MSTR) — have slowed or halted buying in recent months. BitMine remains among the last large-scale buyers of ether-focused treasuries, continuing to provide a steady source of demand for ETH.

BitMine’s total crypto and cash holdings stand at $12.9 billion. In addition to its ETH treasury, the firm holds 199 bitcoin, $1.12 billion in cash and equity stakes including investments in Beast Industries and Eightco Holdings.

Chairman Thomas Lee said the firm sees signs that the recent downturn is nearing an end, pointing to ETH’s rebound and broader market dynamics.

“Bitmine has maintained the increased pace of ETH buys in each of the past four weeks, as our base case ETH is in the final stages of the ‘mini-crypto winter,’” Lee said.

He added that ether has risen sharply from its early February lows and has outperformed equities since the start of the Iran conflict, supported by demand tied to tokenization and AI-related use cases.

BitMine has also continued expanding its staking operations. The firm has staked more than 3.3 million ETH, or about two-third of its holdings, generating roughly $221 million in annualized revenue.
