Strategy, an enterprise software company, holds 840,400 bitcoin valued at about $66.4 billion, based on a price near $79,007 per bitcoin. The stake sits roughly 4.4% above the average cost of $75,653, with unrealized gains over $2.8 billion.

Odaily reported that Michael Saylor posted a chart of Strategy's bitcoin holdings on Sunday, accompanied by the caption 'We’re Back.'

Strategy has not added to its bitcoin position in about two months and typically discloses weekly purchases on Monday mornings. The posting did not indicate whether a new purchase is imminent.

The firm recently raised $334 million by selling MSTR shares and did not deploy those funds into bitcoin, while in recent months it also sold a small amount of bitcoin to cover preferred stock dividends and to fund share buybacks.
