According to @ki_young_ju, publicly traded Bitcoin miner MARA Holdings (MARA) is approaching a significant milestone, with its treasury now holding 49,940 BTC, valued at approximately $5.3 billion. This accumulation solidifies MARA's position as the second-largest publicly traded Bitcoin holder, trailing only MicroStrategy (MSTR), as stated in the company's June update. Despite a 25% monthly decline in blocks won in June due to weather and equipment issues, the company is targeting a 40% hash rate expansion to 75 exahash by the end of the year. For traders, the tight correlation between MARA's stock and the crypto market is evident, with MARA shares falling 2.7% in premarket trading following a recent dip in Bitcoin's price.
