BitMine Immersion Technologies, a prominent digital asset treasury firm specializing in Ethereum, has stepped up its cryptocurrency purchasing pace. According to Chairman Tom Lee, the company is witnessing growing indications that the crypto 'mini-winter' is drawing to a close.

On Monday, the firm announced the acquisition of 101,627 ether (ETH) in the previous week, marking its largest weekly purchase since December 15. This purchase, valued at over $230 million at current prices, has increased BitMine's total ETH holdings to 4.97 million. Notably, this move comes at a time when most digital asset treasury companies, with the exception of Michael Saylor's bitcoin-focused Strategy, have either slowed down or ceased their buying activities. As a result, BitMine has emerged as one of the last major buyers of ether, providing a steady source of demand for ETH.

The company's total holdings of cryptocurrency and cash now amount to $12.9 billion. In addition to its ETH treasury, BitMine holds 199 bitcoin, $1.12 billion in cash, and equity stakes in various companies, including investments in Beast Industries and Eightco Holdings. According to Lee, the firm believes that the recent decline in crypto prices is nearing its end, citing ETH's rebound and broader market trends.

"Bitmine has maintained an increased pace of ETH purchases over the past four weeks, as our core assumption is that ETH is in the final stages of the 'mini-crypto winter,'" Lee stated. He further noted that ether has experienced a significant surge from its early February lows and has outperformed equities since the onset of the Iran conflict on February 28, driven by demand related to tokenization and AI-related applications.

BitMine has also continued to expand its staking operations, with over 3.3 million ETH staked, representing approximately two-thirds of its holdings, and generating around $221 million in annualized revenue.
