BitMine now controls 5.8M $ETH — roughly 4.8% of total supply. 5.07M of that is staked, so they're earning yield instead of just holding.

That's a massive validator concentration. One entity running that much of the network is going to make people nervous, and rightfully so. It's not just about holdings anymore — it's about influence over consensus.

When a single player stakes that much, they're not just an investor. They're a systemic participant. If something goes wrong — technical failure, regulatory pressure, governance decisions — the ripple effects hit the whole chain.

This is the tradeoff with institutional adoption. You get liquidity and legitimacy, but you also get centralization risk. $ETH's decentralization narrative gets harder to defend when one company can sway that much weight.
