MicroStrategy, which remains the largest corporate holder of Bitcoin, will issue $600 million in convertible bonds to buy more BTC.

MicroStrategy shares are up 23% on Monday, February 4, and the share price has risen 172% over the past month. The growth of shares is associated with the growth of Bitcoin, because the company’s wallets hold 193,000 BTC (about $13 billion at the current rate). Therefore, the company’s management decided to issue additional bonds to raise funds for the purchase of bitcoins. The bonds will be valid for 6 years, and holders of securities will be able to sell them or convert them into MicroStrategy shares, or into money.

“MicroStrategy intends to use the proceeds from the sale of the convertible notes to purchase additional Bitcoin and for general corporate purposes,” the company said in a statement.

Note that the average price of bitcoins purchased by MicroStrategy earlier was $31,550. That is, at current prices, the company has doubled the money invested.

Recently, MicroStrategy CEO Michael Saylor said that Bitcoin has entered a period of significant growth and adoption by large investors that will last for the next ten years.
