According to @ki_young_ju, a JPMorgan report reveals that while the Bitcoin (BTC) network's monthly average hashrate dipped approximately 3% in June due to seasonal heatwaves affecting U.S. miners, overall mining profitability has improved. The report highlights that daily block reward gross profit increased by 13% month-on-month, reaching its highest point since January. A key trading indicator is the growing dominance of U.S.-listed miners, whose share of the global network hashrate hit a record 31.5%, according to JPMorgan. These miners have boosted their aggregate hashrate by 99% year-over-year, far outpacing the total network's 55% growth. In stock market performance, the total market capitalization of the 13 tracked U.S. miners rose 23% from the previous month, with IREN (+67%) outperforming and Bitfarms (BITF) underperforming (-19%).
