You can also avail of the BTC Gold as long as you have the key to your paper wallet. But there just some complications since you need to follow the rules of the  fork. If you have read the rules then you are good to go but if you are tired of reading and wanted to play safe you can deposit your bitcoin to yobit or any of the exchanges that support bitcoin gold before the fork. Then after the fork you can just return it again to your paper wallet for safe keeping.
