Strategy chair Michael Saylor hinted on Sunday at further Bitcoin purchases, but investors must wait an extra day to learn whether Strategy bought more. An official SEC filing is unlikely before Tuesday because federal offices will close on Monday for Columbus Day. Strategy bought 334 BTC for $28.7 million between September 28 and October 4, bringing holdings to exactly 848,000 BTC, according to an October 5 SEC 8-K filing. Strategy also repurchased about 1.77 million STRC preferred shares for $176.3 million during the same period. Independent analyst Shanaka Anslem Perera said Strategy's third-quarter capital raising largely supported cash reserves and preferred shareholders rather than Bitcoin purchases.
