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
Very well yes, The present bump in BTC fees is due to huge shift of miners from BTC to BCH due to reasons stated above.
But the situation is temporary and people need not worry about this. The rise in BCH prices was systematic pump and prices will dump hardly once again (I can see downfall of $1200 already). Once this happen, BCH mining will again become less lucrative and SHA256 miners will again head towards BTC kingdom.
My suggestion for users is to hold transactions for time being (5-6 days) if not then use those web wallets which make batch payments. Under batch payment system, web wallets accumulate transaction requests, create a batch and process all in single hash. This result in lower fees and wallets in turn give incentive to users in terms of lower fees.
