Bitcoin’s mining difficulty level rose 2.18% on Wednesday to an all-time high. The level changes every two weeks and measures the additional computing power a miner has to use to verify transactions on a block. A higher difficulty indicates it is more competitive to mine Bitcoin, reducing profit. The network’s hashrate also increased to a record high.

  • Bitcoin’s hashrate was at around 392.6 exahashes per second on Wednesday, an increase from the 375.4 exahashes recorded during the previous adjustment on June 1, data from shows.
