MicroStrategy, the technology company known for its significant positions in Bitcoin, has completed its $ 1.05 billion offer in convertible senior notes - a money which the company plans to use to buy even more Bitcoin.

A convertible senior note is a type of debt security that can be converted into shares or repurchased by the issuer; they are set to mature in 2027, but MicroStrategy can buy them back in 2024.

The CEO Michael Saylor remains a strong supporter of Bitcoin at the institutional level - the company currently has more than 70,000 Bitcoins (about $ 4 billion).

The bet has worked very well for MicroStrategy so far (stock prices have been quite high since its first investment in August last year), but not everyone is happy: Citi analysts recently downgraded the company's shares, citing overconfidence on Bitcoin.
