Better you can wait if there is no urgency. Most of them don't have any idea to decide to go which way about the btg yet.. Holding it tight will make sense
Yes,what you have to do is export your private key from exodus wallet and keep it safe.Send bitcoins back to coinbase.Since BTG fork will activate after November 1 you can be sure you won't be affected by replay protection if you transfer your bitcoin now to another address even though BTG fork already have replay protection(as they claim).
I think, We never confirm about replay protection as of now.
