Strategy, the bitcoin-hoarding firm founded by Michael Saylor, said it sold 1,690 bitcoin last week to fund preferred stock repurchases.

The sale, which raised about $109 million, marks the company's second week of consecutive bitcoin sales. Strategy said last Monday that it had offloaded about $105 million worth of the cryptocurrency in the prior week.

Strategy also sold about $653.1 million worth of common stock shares mainly to boost its U.S. dollar cash reserves, which stood at $4.65 billion as of Sunday.

Shares of Strategy were flat in premarket trading. Bitcoin recently traded around $65,000.
