There are speculations about what is going to happen once Bitcoin retargets its difficulty, in 7 hours.
This is relevant because its the beginning of the fist full mining cycle of 2016 blocks since Bitcoin Cash forked to its new difficulty adjustment algorithm. And there is a scenario in which Bitcoin price dumps, thus mining moving to Bitcoin Cash (assuming stable or rising price) and thus slowing down the Bitcoin block time. Now this leads to even greater block space scarcity resulting in even higher fees. Those high fees are a pretty clear incentive for people to move to a more efficient network, selling BTC for BCH and you pretty much end up with a positive feedback loop.
