Section 01
The Week
Marathon Digital sold 15,133 BTC ($1.1 billion) on March 25th, the week's largest transaction by USD value, per an 8-K filing. The sale occurred as BTC traded near $72,700, marking a notable reduction in the company's treasury position. Offsetting the sell, Strategy acquired 1,031 BTC ($77 million) on March 23rd, while BTCS Inc made a significant move into Ethereum, purchasing 10,000 ETH ($18.7 million) on March 26th. Bit Digital added 730 ETH ($200,000) the same week. Bitcoin Depot trimmed holdings by 50.903 BTC ($3.7 million). Five distinct companies filed activity; no new stackers entered the cohort.

Notable Filings
Marathon Digital's 8-K (March 25) discloses the 15,133 BTC sale, representing a deliberate portfolio reduction during a flat-to-down week for bitcoin price. Strategy's 10-K filing (February 23, dated but reflected in filings this week) notes the 1,031 BTC acquisition at an average cost near $74,700 per coin. BTCS Inc's 10-K (March 26) documents the largest Ethereum purchase by a treasury filer this year: 10,000 ETH at an effective price of $1,870 per token. Bit Digital's 10-K (March 27) includes a smaller ETH position of 730 tokens. Each filing carries the company's rationale in its MD&A or item 8.01 language.

One Chart
Marathon's $1.1 billion BTC sale dwarfs all other activity this week by an order of magnitude, yet the cohort's net position swung only modestly negative because Strategy, BTCS, and Bit Digital bought simultaneously. The week's true signal: Ethereum broke into the corporate-treasury conversation with two distinct filers acquiring 10,730 ETH in aggregate. ETH treasury adoption remains thin compared to BTC, but BTCS's entry at scale suggests a strategic reframing beyond the bitcoin-only consensus.
