Odaily Planet Daily News JPMorgan Chase said in a research report that the combined hash rate of the 14 U.S.-listed bitcoin mining stocks tracked by the investment bank currently accounts for 28.9% of the network hash rate, a record high. Analysts Reginald Smith and Charles Pearce wrote: "The total hash rate of the 14 U.S.-listed miners tracked has increased by about 70% (80 EH/s) so far this year to 194 EH/s, while the network hash rate has increased by 33%, currently accounting for a record of about 28.9% of the global network hash rate." The bank said that this figure has increased by nearly 8% since the Bitcoin halving event earlier this year, reflecting the efficiency and financing advantages of some listed miners. In addition, mining stocks rose in the first two weeks of this month as Bitcoin rose, while companies in the field of high-performance computing (HPC) continued to attract interest from hyperscale corporate transactions.
