BitMine Immersion Technologies has disclosed that it now holds 5,390,404 ETH, approximately 4.47% of Ethereum's total supply, as part of its strategy to own 5% of the network. This accumulation, achieved at an average price of $2,134 per ETH, marks a significant increase from its December 2025 holdings of 4.11 million ETH. The company has also staked around 4.71 million ETH, potentially generating $276 million annually at current yields. The rapid acquisition and staking by BitMine have sparked debates about the implications for Ethereum's decentralization. As a publicly listed company, BitMine's substantial stake and validator operations could influence Ethereum's governance and security, raising concerns about increased centralization and regulatory pressures. While markets view this as a sign of institutional adoption, critics warn of potential risks to the network's resilience and independence.
