I think nothing will happen in November, and if something happens, the bitcoin will drop slightly to get back up again, so do not worry about the split.
in that case which will you take as real bitcoin.bitcoin segwit2x or bitcoin core?if forks happens which looks possible then it will damage the image of bitcoin and cause confusion.segwit2x has more then 90% support but core has good developers the safest option will be to hold both the coins and wait it out.people should know to not be greedy and dump one coin for another as they may lose their coins if the coin they dump turned out to have less support from investers,miners,users.
