Jamie Redman reports in bitcoin.com that "as expected, Bitcoin’s mining difficulty increased this week jumping 6.03% higher on July 31. The change marks the first increase out of five difficulty adjustment changes. This was after four downward difficulty drops made it 54% easier to mine bitcoin than it was prior to mid-May.
While the last four difficulty changes made it 54% easier to mine than before May 13, the difficulty increased for the first time in eight weeks by a touch over 6%. This is because miners who went offline during the crackdown in China, have seemingly returned to some extent.
Despite the increase on Saturday, BTC blocks are still 48% easier to find today than they were before May 13, 2021. Estimates show on Sunday that the difficulty is expected to rise again in 11 days and increase around 1%. However, depending on hashrate speed, the estimate could change higher or lower as the countdown gets closer."
