Mining difficulty in Bitcoin refers to how challenging it is for miners to solve the puzzles that confirm transactions and add blocks to the Bitcoin blockchain. The difficulty shifts with changes in hashrate and miner activity, sometimes pushing miners to upgrade rigs, expand data centers or rethink their strategies.
Despite the surge in mining difficulty, both Riot and CleanSpark reached a significantly higher average operational hash rate year-over-year.
Riot’s average operational hash rate rose to 31.4 EH/s in August 2025 compared to 14.5 EH/s in August 2024, a 116.6% jump over the past year. CleanSpark’s rose to 43.3 EH/s from 21.3 EH/s, representing a 103.3% increase during the period.
Some miners are choosing to branch out from Bitcoin mining, exploring incremental sources of revenue. For instance, Hut 8 for high-performance computing, such as artificial intelligence workloads.
