Foundation distributed 27k ETH this week. BitMine staked 112k. What are we actually watching here?

The Ethereum Foundation (EF) staked ETH up to its target, then sold 10,000 ETH OTC to BitMine and unstaked 17,035 ETH via Lido. BitMine and Grayscale staked nearly $500M of ETH during the same period, raising questions about coordinated institutional demand and EF's role in ETH price dynamics.
