The enterprise software maker, whose corporate strategy includes buying the cryptocurrency, bought the tokens between Nov. 11 and Nov. 17, according to an US Securities and Exchange Commission filing on Monday. It now holds more than $29 billion in Bitcoin.

MicroStrategy co-founder and Chairman Michael Saylor decided to invest in Bitcoin in 2020 as a hedge against inflation. The firm initially used cash to make the purchases, and has shifted to using the proceeds from the issuance and sale of stock, as well as convertible debt sales to leverage its buying power.

Saylor has doubled down on the strategy this year, saying the company aims to raise $42 billion over the next three years.
