ETH-native volume this week ($1.46 billion) eclipsed BTC-native volume ($354M) by a factor of four — the first week in the tracked period where Ethereum purchases dominated by USD value. BMNR's single transaction accounts for 99.4 percent of weekly ETH additions. For the BTC cohort, the two corporate stackers (Strategy and Marathon) combined for $354M in acquisitions, keeping pace with spot-ETF inflows and maintaining corporate treasury as a measurable — if secondary — source of on-chain demand.
