If at the time of the hard fork november 15 you will in bitcoins, then be sure to keep them on exchanges, otherwise you will not be able to make deposits for sale, both sides do not want to put protection from repeated transactions
This is terrible advice, I'm sorry. Which exchange allows you to keep your private keys? I have yet to hear/see one. Rule number is that whatever wallet you keel your coins in, make sure you have access to your keys. Let exchanges and wallet developers worry about replay protection. As a user your only worry is your keys, unless you are dumb enough to do transactions immediately after the fork. Your coins will go no where, you can wait a few days, until developers have done their jobs.
