Golden Finance reported that Bitcoin mining company Marathon Digital recently sold $300 million in convertible notes to purchase 4,144 bitcoins, following MicroStrategy's strategy. This move reflects the plight of the mining industry: mining profits have dropped sharply, and mining companies have to maintain operations through other means. Marathon recently announced on X that instead of buying more mining equipment, "given the current mining hash price, the internal rate of return (IRR) shows that it is more beneficial to shareholders to use funds from debt or equity issuance to purchase Bitcoin before the situation improves." "Hash price" is a measure of mining profitability. "Adopting a comprehensive HODL strategy reflects our confidence in the long-term value of Bitcoin. We believe that Bitcoin is the best treasury reserve asset in the world and support the idea of ​​sovereign wealth funds holding Bitcoin. We encourage governments and companies to hold Bitcoin as a reserve asset."
