MicroStrategy, one of the world’s largest public holders of Bitcoin, continued stacking BTC even as the cryptocurrency broke new highs.

On Nov. 18, MicroStrategy announced it purchased 51,780 Bitcoin ( BTC ) for about $4.6 billion at an average price of $88,627 per BTC.

MicroStrategy uses fresh proceeds from a share sale

To acquire thousands of new BTC, MicroStrategy used fresh proceeds from a share sale under a sales agreement with companies like TD Securities made on Oct. 30.

Between Nov. 11 and 13, MicroStrategy sold 13.6 million shares for $4.6 billion.

As of Nov. 17, the company reported about $15.3 billion in shares still available for sale under the agreement, according to a filing with the United States Securities and Exchange Commission.

The purchase came amid Bitcoin breaking past $90,000 for the first time in history on Nov. 12 and extending gains further to a new high above $92,400 the next day.

This is a developing story, and further information will be added as it becomes available.
