Bitcoin mining difficulty surge by 7.96%
In the past seven days, Bitcoin’s mining difficulty increased by around 7.96% to 126.27 trillion. The difficulty adjustment took place at block number 905,184. That’s the ninth increase in difficulty so far this year. In contrast, the BTC network saw five difficulty decreases occurring during the same period.
The network’s difficulty decreased by 0.11% over the last 30 days; however, it surged by 3.92% over the past 90 days.
The next Bitcoin difficulty adjustment is estimated to occur on Saturday, July 26. Data indicates that the upcoming adjustment will lower the mining difficulty from 126.27 trillion to 123.19 trillion.
Bitcoin difficulty adjusts every 2,016 blocks, or approximately every two weeks. This mechanism keeps the average block confirmation time at about 10 minutes.
The recent jump to 126.27 trillion is a result of the rise in total mining power across the network.
Bitcoin has dipped by 0.9% from its all-time high of $122,838. At press time, the coin is exchanging hands at $121,760, with a 24-hour trading volume of $59.2 billion. BTC’s market cap stands at $2.4 trillion, with a market dominance of 62.4%.
