Bitcoin staged a 10% sell-off over the weekend, but MicroStrategy viewed the correction as a buying opportunity, according to a filing made with the SEC on Monday.

MicroStrategy purchased 328 more bitcoin for $15 million, representing an average price of $45,710, according to the filing. Bitcoin fell to a low of about $43,000 on Sunday, but it has since rallied 14% to $49,000 after Citi said the cryptocurrency was near a "tipping point" of going mainstream.

MicroStrategy's stake in bitcoin is now worth about $4.5 billion. The firm has continuously piled into bitcoin since August 2020. Most recently, the firm raised about $1 billion in debt to add to its stake.

MicroStrategy now owns a total of 90,859 bitcoin at an average price of $24,063, inclusive of fees and expenses. The firm has paper gains in bitcoin of about 100%.

Shares of MicroStrategy traded up as much as 6% in Monday trades, and are up 93% year-to-date.
