Crypto World News reports that, influenced by the sharp decline in Bitcoin prices in early June, Bitcoin mining difficulty is expected to decrease by approximately 9.55% in about eight hours.

This will be the second-largest drop of the year, reducing the computational effort required to produce blocks over the next two weeks, thereby directly increasing the unit hash rate earnings for active miners on the network.
Analysis indicates that if the coin price and network transaction fees remain stable, this 9.55% difficulty adjustment will boost BTC output per active hash rate by over 9%, potentially driving the network hash rate back above $30/ph/s.
Apart from economic incentives prompting older mining machines to shut down voluntarily, another major driving force behind the decline in hash rate is the transformation of some power generation capacity toward high-performance computing (HPC) and AI data centers.
