Bitcoin mining difficulty today increased by 3.87%, reaching 138.97T. The total network hash rate over the past seven days is also around 986.74 EH/s. The continued rise in difficulty indicates that competition among miners is intensifying. In the short term, this puts pressure on miner profits, but it also indirectly shows that the network hash rate remains strong. For $BTC , such news usually does not immediately change the price trend, but if the price later fails to keep up with the rising difficulty and hash rate, selling pressure and emotional fluctuations among miners may be amplified. The short-term rhythm remains cautious.
