BitMine Immersion Technologies (BMNR) Stock Today: Cathie Wood Buys the Dip as BitMine Pushes Toward 5% of Ethereum Supply
December 16, 2025 — BitMine Immersion Technologies, Inc. (NYSE American: BMNR) is back in the spotlight after a sharp selloff in crypto-linked equities collided with two very “BitMine” storylines: aggressive Ethereum accumulation and big-ticket institutional buying. On one side, BMNR stock slid hard alongside a broader risk-off move in digital assets. On the other, Cathie Wood’s ARK Invest stepped in with a sizable purchase, and BitMine itself reported that its Ethereum position has grown into a jaw-dropping chunk of total supply—now framing the company less like a traditional miner and more like an Ethereum treasury vehicle with a public-market wrapper.
