First, I will make a few assumptions of your real intentions:
- you know how to create and deposit to your paperwallet
- you still want to keep 1
BTC safely in a cold storage
- you simply want to claim your share on the fork chains and exchange to
BTCWhat I would suggest you to do:
1. move your 1
BTC to another new paperwallet,
if you want to keep it stay at 1
BTC, you have to combine/add another input in th tx
2. you could use bc.info or BCH wallet and send to exchange, bc.info only support BCH at the moment
3. do the same for BTG or other fork coins and send to exchange
yes... you can repeat the redeem process on all fork chains
4. exchange them to
BTC and withdraw to your paperwallet or any address you want
5. your original
BTC+more will be safe in new paperwallet and will be eligible for future forks
just a small note here, try to find a trusted exchange that support all (/most) those fork coins
it would save you good amount of withdrawal fee
