    Bitcoin network difficulty experienced the largest drop ever with a 27.94% decrease or 5.8 T on July 3rd. As a result, the average block time during that period increased from 10 min per block to close to 14 min.

    The difficulty decrease was produced by a sudden drop in hashrate from around 100 EH to 58 EH, but it recovered swiftly back to 94 EH. Despite this sudden drop, the average hashrate during the last 2 weeks remained 102.78 EH/s.

    Bitcoin Difficulty

    With Bitcoin’s internal balancing mechanism, mining becomes more profitable with less hashrate competition as the nonce grinding becomes easier to solve.
