People like Roger Ver that want to lift on the succes of Bitcoin.
They are trying to substitute Bitcoin core by spamming the network and doing controlled pumps.
This will make BCH more profitable to mine, so a lot of core miners will mine BCH which slows down the transaction times of BTC network. This causes high transaction fees and basically and unattractive coin to use for micro payments.
Mining pools who are recently swapped to BCH to mine it when the bitcoin is the good rate. Because of the miners movement I see that bitcoin value started dumping in the chart and BCH is bumping but I think soon they will return to bitcoin. When they are mining bitcoin also they were getting the decent profit only. Really confuse that they move to BCH and bumping that. Stupid miners.
Its nothing strange that miners are driven by profits, you may say they are short-sighted, but they are not stupid, i think if btc community cant balance the interests of all parties, such things will appear more than once
