Michael Saylor’s Strategy Inc. bolstered its cash reserve to $2.19 billion and paused purchases of Bitcoin over the past week as the largest digital asset treasury company appears to be settling in for a long crypto winter.

The Tysons Corner, Virginia-based firm raised $748 million through the sale of common shares in the seven days ended Dec. 21, according to a filing Monday with the US Securities and Exchange Commission. It had purchased about $2 billion in Bitcoin over the previous two weeks, bringing its total holdings to around $60 billion.
