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
I think this goes against common sense. Leaving all your coins on exchanges exposes you to incredible third party risk. And the fact that there is no replay protection makes this even riskier: what if an exchange screws up their internal replay protection and ends up losing lots of coins?
Or what if this ends like like Bitcoin Cash or Ethereum Classic on Coinbase, where it takes them many months to give people their minority chain coins? There is also no guarantee that any given exchange will support markets for both coins. Bitfinex will definitely offer markets for both, but I'm not sure what everyone's policy will be.
What would be the safest method for you? Keep your coins in a wallet (with private keys) until the dust settles after the fork? Are there any negative effects of such a method?
