Notable Filings
Strategy acquired 390 BTC for $43.0M at roughly $111,000 per coin, continuing its consistent buying cadence. Virtu Financial's 10-Q filing disclosed treasury positions of 1,432 BTC and 718 ETH, filed October 30. BitMine's balance disclosure surfaced its dominance in the ETH cohort—3,313,069 ETH total, a $317.6M cumulative gain since the prior filing. Def Consulting (4833.T) and Quantum Solutions (2338.T) accumulated 1,252 ETH and 500 ETH respectively across multiple tranches, signaling sustained institutional ETH appetite. Riot Platforms (RIOT) disclosed 19,287 BTC total, a negligible 14 BTC net addition since last period.

ETH filings now represent 30% of this week's transaction volume by distinct company count (3 of 8), though Bitcoin dominates by USD value at 92% of $70.1M. BitMine's large balance disclosure masks a structural shift: corporate ETH stacking occurs in smaller, more frequent increments than BTC. The per-token rolls show 2,086 ETH in weekly purchases against 2,469 BTC, yet BTC captures $64.5M to ETH's $5.5M—reflecting Ethereum's lower per-unit price and narrower corporate adoption base relative to Bitcoin's institutional anchor.
