Are you saying that Bitcoin ABC may be a malicious player?
Potentially. Put it this way, this is the first I heard of any chain split, but there is plenty of time to hash it all out. Have ABC stated they will be forking regardless?
ABC can not FORK! ABC is a protocol dev. team. Only miners can fork, by running code. ABC Team suggested some changes, it is now on miners so articulate if they are willing run it.
