summary of what happened:
- August 1st BCH was created to attack bitcoin, they implemented EDA or difficulty manipulation
- SegWit2x was suspended
- BCH pumpers used this to FUD bitcoin and pump BCH
- higher price of BCH + lower manipulated difficulty => incentive for miners to switch
- sudden lower hashrate on bitcoin + no difficulty manipulation => temporary harder to find blocks
- lower number of blocks found => bigger mempool => higher fees.

all will be fine soon
- difficulty adjustments will start + the BCH pump will end => incentive to mine BCH is removed
