BMNR is trading at 4% down now at $51.66 after a sharp 7.92% gain on October 20, 2025, when the company disclosed it had become the world's largest Ethereum treasury holder, acquiring over 200,000 ETH in a single week and pushing its total holdings to 3.24 million ETH, representing 2.7% of the total supply[1][5][6]. The stock's recent volatility reflects both the market's reaction to this aggressive crypto accumulation strategy and potential profit-taking after the rapid ascent. No new major company-specific news has emerged on October 21, 2025, suggesting the current decline may be a technical pullback following the prior rally, rather than a new fundamental catalyst.
