Bitmine has acquired a significant amount of ethereum, with reports indicating the company has purchased tens of thousands of ether in a short period. The exact amount is unclear, with estimates ranging from 71,000 to over 100,000 ether, but it appears to have brought the company's holdings to around 4-5% of the total ethereum supply. The acquisition is reportedly part of the company's efforts ahead of a potential NYSE listing, although the details and implications of the purchase are still emerging.
