BitMine Immersion Technologies (BMNR) stock fell -8.40% to $29.57 during live trading on November 19, 2025, continuing a multi-day decline despite announcing a major purchase of over $173 million in Ethereum and engaging Tom DeMark and DeMark Analytics as strategic advisors. The company now holds 3.6 million ETH, expanding its crypto treasury even as the broader crypto market, including Bitcoin and Ethereum, experiences notable weakness. The sharp drop in BMNR shares appears linked to ongoing crypto market declines and investor concerns about market-maker stress, as highlighted by recent commentary. Despite the company's aggressive accumulation of Ethereum, negative sentiment in digital assets is weighing heavily on the stock.
