Notable Filings
Strategy's 168 BTC purchase on October 20th at an average of $112,051 per coin represents continued accumulation into a period of price volatility and extreme fear sentiment (CNNMoney Fear & Greed Index at 22). Quantum Solutions (2338.T), a Japan-listed entity, entered the ETH treasury space with 2,000 ETH ($7.8M), becoming the cohort's eleventh-largest holder on first filing. BitMine Immersion Technologies' disclosed position of 3,236,014 ETH ($1.6B net change) dwarfs all discrete weekly purchases — a multi-period accumulation surfacing in a single filing. Vanadi Coffee (VANA) executed five separate BTC purchases totaling 11 BTC across October 17–23, averaging $111,400 per coin, consistent with a dollar-cost-averaging cadence.

ETH filings this week approached parity with BTC on count — two distinct companies buying ETH against four buying BTC — yet USD value remained skewed: BTC dominated at $21.3M versus ETH's $8.2M. This reflects Quantum Solutions' entry weight; the cohort's median ETH buyer remains smaller by ticket. Meanwhile, BitMine's 3,236,014 ETH disclosure exposes how extreme positions emerge through multi-period filings rather than weekly snapshots.
