Ethereum treasury firm BitMine deposited 159,728 ETH (approximately $390 million) into the staking protocol, bringing its estimated total staked holdings to over 5.227 million ETH (roughly $12.8 billion). The move coincides with a significant bottleneck in Ethereum's staking infrastructure. The entry queue currently holds 1.33 million ETH, resulting in wait times exceeding 23 days for new validators. In contrast, the exit queue contains only 149,000 ETH, with wait times under four days.
