The Bitcoin Cash (BCH) network will be forking on the 15th November at approximately 11pm Sydney time.
The fork itself is expected; the network forks every 6 months, however there is a potential for this fork to be contentious due to some conflicting ideas about the future direction of the cryptocurrency. A contentious fork will sometimes lead to two resulting blockchains and cryptocurrencies.
At time of writing it appears the vast majority of miners are signalling in one direction, so it is possible the fork will not be contentious, but time will tell and we will keep you up to date.
