Bitmine Immersion Technologies, the world’s largest public holder of Ether, significantly expanded its treasury with a purchase of 101,627 ETH last week. According to an SEC filing, the buy marks its largest since December 2025 and brings its total holdings to nearly 5 million ETH, valued at approximately $11.5 billion. The company’s chairman, Tom Lee, stated the continued purchases reflect a view that Ether is in the final stages of a “mini-crypto winter.”
Bitmine Immersion Technologies acquired 101,627 ETH during the week of April 13 to 19. The purchase was detailed in a press release and an accompanying Form 8-K filing with the U.S. Securities and Exchange Commission.
Chairman Tom Lee called this the company’s largest Ether buy since December 15, 2025. “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.
Following the purchase, Bitmine said it held 4,976,485 ETH valued at roughly $11.5 billion. The company also holds 199 Bitcoin, a $200 million stake in Beast Industries, a $107 million stake in Eightco Holdings, and $1.12 billion in cash.
The company’s total crypto and cash holdings now stand at $12.9 billion. This update extends Bitmine’s lead among public company Ether treasuries.
In holding 4.98 million ETH, Bitmine now owns more than 4% of the total Ether circulating supply. The company said its broader goal remains to reach the “alchemy of 5%.”
The purchase came after Bitmine recently started trading on the New York Stock Exchange. The company uplisted from the NYSE American as it expanded its share buyback program.
Bitmine has also expanded its staking operations through its MAVAN platform. The company reported that 3.33 million ETH is currently staked, generating annualized staking revenues of over $200 million.
At Paris Blockchain Week 2026, Lee described the recent crypto slump as a “mini crypto winter.” He predicted that Ether could climb above $60,000 over the next few years.
