MicroStrategy Inc. bought $1.1 billion of Bitcoin, as the company gears up for a shareholder vote on a 30 times increase its authorized Class A shares.

MicroStrategy added to its bitcoin stash for the 11th week in a row, as the company's investors get ready to vote on increasing its Class A and preferred stock and enhancing its ability to buy more bitcoin.

MicroStrategy—which almost exclusively focuses on securitizing Bitcoin—last year announced a “21/21 Plan” to raise $46 billion to buy even more Bitcoin. The plan would see the firm raise $21 billion via equity, with another $21 billion coming by selling fixed income securities.
