BitMine Immersion Technologies, the largest corporate Ether holder, purchased 28,086 ETH (≈$70M) in the week through Sept 7, pushing its treasury to roughly 5.93M ETH (≈$14.8B), just shy of its stated 5%-of-supply target. Chairman Tom Lee remains bullish, citing ETH's outperformance versus the S&P 500 this quarter.
Matters because: Continued accumulation by a major corporate treasury may support ETH price stability by reducing available float.
