The bitcoin cash blockchain has seen five downward difficulty adjustments after struggling to produce blocks yesterday. Blocks 481,878 through 481,882 each pushed down the difficulty (the mechanism that regulates reward release) under the network's "emergency difficulty adjustment rule" which adjusts difficulty down 20%, making it easier for miners to find blocks and claim rewards.
As a result, the difficulty adjustments succeeded in bringing the hash rate to about 10% of bitcoin's hash rate, which made bitcoin cash more profitable to mine – even with the extra fees that bitcoin offers from its increased user base.
