Bitmine buys 42,197 ETH, boosting its stock as rival Strategy sells Bitcoin

Bitmine Immersion Technologies said it added 42,197 ether to its treasury between June 29 and July 6, extending a larger Ethereum bet that helped lift the company’s stock more than 4% on the day.

The purchase came as Strategy, the best-known corporate Bitcoin buyer, saw its shares edge lower after disclosing a Bitcoin sale. That split screen has put fresh attention on two very different treasury strategies, one centered on ETH accumulation and the other on a more cautious posture around BTC.

Bitmine did not give a dollar figure for the latest buy in the source material, but the size of the addition is notable on its own. The company has been expanding its ether holdings at a time when Ethereum has drawn renewed institutional attention, helped by the prospect of deeper balance-sheet adoption among public companies.

For investors, the market reaction was straightforward. BMNR moved higher on the ether purchase, while Strategy lost ground as traders digested the optics of a Bitcoin sale from a company that has built its identity around aggressive BTC accumulation.

The contrast matters because treasury moves are now part of the trade in both stocks. When a listed company adds crypto to its balance sheet, the announcement can quickly feed into share price action, especially when the asset being bought is one that the market is already debating.

Bitmine’s update also lands against a wider backdrop of rivalry between Bitcoin and Ethereum as corporate reserve assets. Strategy remains the most closely watched proxy for Bitcoin-heavy treasury management, while Bitmine is emerging as a more direct Ethereum play. That makes each disclosure, buy or sale, something traders will read closely for clues about near-term appetite.

The next item to watch is whether Bitmine gives another treasury update or discloses a fresh ETH purchase, and whether Strategy follows its sale with further commentary on capital allocation. For now, the market has made its preference plain: more ETH helped BMNR, while a BTC sale weighed on Strategy.
