BitMine Immersion Technologies has significantly increased its Ether holdings, acquiring $200 million worth of ETH from Bitgo. This marks BitMine's second major purchase this week, totaling 46,255 ETH across three transactions. The company's total holdings now exceed 2.1 million ETH, valued at over $9.2 billion, solidifying its position as the largest public company holder of Ether. This week's acquisitions nearly match the total ETH bought by treasury firms last week. In contrast, Bitcoin treasury purchases have slowed, with public firms acquiring only $60 million worth of BTC since Monday. Despite the slowdown, companies like Pop Culture Group and Robin Energy saw significant stock price increases following their Bitcoin purchases. Meanwhile, other firms such as QMMM Holdings and Eightco Holdings experienced volatile stock movements after announcing plans to invest heavily in cryptocurrencies.
