According to Internet reports, JPMorgan analysts wrote in a report on Tuesday that last month, some large mining companies expanded into high-performance computing, driving the overall market value of listed Bitcoin mining companies to soar. In August, the total market value of 13 listed mining companies in the United States hit a new record, exceeding US$39 billion. Mining companies tracked by JPMorgan include Hut8, Core Scientific, TeraWulf, IREN and Riot, all of which are listed on the stock exchange. Mining this type of cryptocurrency, the world's largest by market value, has become increasingly difficult and costly. Since halving last year, the block rewards for Bitcoin mining have dropped from 6.25 to 3.125, and output has decreased. These trends have weakened the profitability of mining companies, prompting miners to seek new sources of income even as bitcoin prices rise.
