Bitcoin mining difficulty today increased by 3.87%, reaching 138.97T. The total network hash rate has also been around 986.74 EH/s over the past seven days. 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 network hash rate has not relaxed. For $BTC , such news usually does not immediately change the price trend, but if the coin price fails to keep up with the rising difficulty and hash rate, miner selling pressure and emotional fluctuations may be amplified. The short-term momentum remains cautious.
