Another big player in the market, ETH whale MicroStrategy Bitmine, seems to have entered defense mode. Not only did their weekly purchase volume hit a new low, with only 44,000 ETH added last week, but they also officially announced for the first time that some of their tokens have been staked. Next, the company plans to fully push its own staking nodes to ensure that after holding a large amount of ETH, they stake it themselves to generate more ETH. Seems like they've shifted from aggressive accumulation to staking defense.
