Looking at fork.lol charts BCH hashrate just went to double that of BTC, its currently more than 50% of the total hashrate.
It seems like most of the miners moved to BCH and more are following, at this pace bitcoin core will be dead very soon since it will be even more difficult to confirm transactions.
In two hours BCH will be 4x harder to mine. The miners will migrate back to BTC. They only care about which coin makes them the most money and this was all coordinated to mess with Bitcoin as much as possible.
Soon enough things will be back to relative normal. You can't coerce an entire system with those tactics.
