Mining company Marathon Digital announced the placement of $250 million in convertible bonds to purchase bitcoins, as well as for “general corporate purposes.”

The unsecured notes, which mature in 2031, will be offered to corporate investors, Marathon Digital said. Buyers can exercise an option to purchase an additional $37.5 million in bonds.

Last month, the company increased its bitcoin reserves to 20,818 BTC ($1.14 billion). In July, 692 BTC were mined. On July 25, $100 million worth of purchased bitcoins were added to the balance.

Marathon Digital CEO Fred Thiel (Fred Thiel) stated that the company will continue to adhere to the “full HODL” strategy. The strategy involves preserving the acquired assets with the subsequent acquisition of the first cryptocurrency by attracting additional capital.

According to Fred Thiel, investing in Bitcoin is profitable for the company, since in the long term the rate of the first cryptocurrency will update its historical maximum.

Earlier, experts from the Bitfinex cryptocurrency exchange said that Bitcoin is an effective safe-haven asset. According to analysts, the value of the first cryptocurrency increases even more during an economic recession.
