A pair of large on‑chain movements has sparked fresh questions about whether big institutional holders are selling Bitcoin — or simply shifting custody. What happened - On Aug. 5, on‑chain analytics firm Lookonchain flagged a transfer of 1,030 BTC (about $66.1 million) from addresses it identifies as linked to Michael Saylor’s company, Strategy. The move came two days after Strategy disclosed a separate Bitcoin sale, prompting renewed attention on the firm’s evolving treasury approach. - Lookonchain’s post asked, “Is Michael Saylor’s Strategy dumping BTC again?” — a question the analytics firm posed with the caveat that address attribution and an on‑chain transfer do not by themselves prove a sale. Why it’s unclear if this was a sale - Strategy has not confirmed that the 1,030 BTC transfer was a sale. Its latest SEC filing (cutoff Aug. 2) reported holdings of 842,138 BTC; that figure had not been revised in filings available at the time of reporting. - On‑chain movements can reflect many non‑sale activities: transfers between custodians, internal wallets, trading and settlement accounts, or other asset‑management operations. Confirmation of a sale would require a company disclosure, an identifiable exchange deposit followed by trading, or similar evidence. Context from Strategy’s recent disclosures - Strategy officially reported selling 1,638 BTC between July 27 and Aug. 2, receiving $104.73 million after fees (an average of $63,957 per BTC). The company used $52.4 million to fund preferred stock dividends and $52.3 million to repurchase STRC preferred shares, and separately bought back 912,143 STRC shares for $81.2 million in the period. - Strategy’s public ledger (which records transactions the company itself reports) still lists 842,138 BTC. The company’s board approved a Bitcoin monetization framework in June that permits sales to support cash reserves, pay dividends or interest, and finance approved security repurchases — but it does not mandate any specific sales quota. - Strategy’s ledger also shows four reported 2026 sales totaling 5,258 BTC, signaling a shift from its prior focus on continuous accumulation. MARA move raises similar questions - Lookonchain also reported a 6,000 BTC transfer (about $384.6 million) from Marathon Digital Holdings (MARA) to addresses it associates with Two Prime, a crypto asset manager. The analytics firm warned this “doesn’t necessarily mean a sale” and could be related to asset management or custody shifts. - MARA has an existing relationship with Two Prime: it led a $20 million investment in July 2025 and expanded a managed allocation from 500 to 2,000 BTC. An SEC filing showed MARA moved 2,000 BTC into a separately managed account in 2025; that account held 1,903 BTC by Sept. 30 after a net trading loss of ~97 BTC. - MARA’s publicly reported holdings were 36,303 BTC (approx. $2.34 billion). The miner has said it may buy or sell Bitcoin depending on market conditions and capital allocation needs; in March it sold 15,133 BTC to support a $1 billion convertible debt repurchase and subsequently increased holdings to 36,303 BTC in June. Market reaction and next steps - At the time of reporting, Bitcoin traded near $64,387, up about 0.95%. Strategy shares rose roughly 2.9% to $97.65, while MARA was essentially flat at $11.75. There was no immediate broad market selloff tied to the transfers. - Both the Strategy and MARA movements should be treated as transfers until companies disclose details. Strategy says it will report material Bitcoin monetization through Form 8‑K filings and its public dashboard; a future update would reveal whether the 1,030 BTC movement reduces its reported holdings. MARA investors likewise need an SEC filing or company statement to confirm whether the 6,000 BTC remains on the company’s balance sheet or has been monetized. Bottom line Large, labelled transfers from institutional addresses are headline‑grabbing, but they don’t automatically equal sales. On‑chain attribution is useful for tracking flows, but corporate disclosures remain the definitive source for confirming whether a move represents a monetization of holdings.

Summary
On-chain trading signals show two major Bitcoin transfers have sparked speculation about potential sell-offs or custody shifts. On Aug. 5, 1,030 BTC (about $66.1 million) moved from Michael Saylor’s Strategy addresses, while Marathon Digital shifted 6,000 BTC (about $384.6 million) to Two Prime. Lookonchain notes on-chain activity may reflect internal management rather than sales. Strategy’s SEC filing as of Aug. 2 shows no change in holdings. Market reactions were muted, with Bitcoin near $64,387, and support and resistance levels remain key for traders to watch.
