How to transact my bitcoins after hard-fork without losing the forked altcoins (i.e., bitcoin diamond, BCX, Super Bitcoin, etc) which lack of replay attack protection except for export my private key and recovery phrase?

Current status: In order to gain various hard-forked altcoins, I stored my bitcoins into my hardware Ledger Nano S wallet before hard-fork. After hard-fork, I am going to move my bitcoins from my hardware wallet into exchanges for transaction. As some of the hard-forked altcoins have no replay attack protection and no new launched corresponding wallets by the Dev, if I move my bitcoins to exchanges the altcoins will be moved and I will lose the ownership of these altcoins.

Question: I am wondering how I can use my bitcoins without losing my hard-forked altcoins.

I appreciate your help.  

 

AFIAK, all these forks will have replay protection. In case if it's not. You can do following steps. Pick up exchange which has split these coins. It would be exchange what trading those forks (NOT futures but actual coins). Withdraw some bitcoins from that exchange. Join your bitcoins with output from exchange and send this transaction back to exchange in one transaction (join inputs). It would be valid transaction in bitcoin network, but invalid in fork chain and you keep you fork coin.

Don't follow the bitcoin diamond  fork and Ledger Nano S wallet is good wallet to use during fork but I don't know if Ledger support the fork. Incase, they don't look for a wallet that support it, import private keys and claimed your BCD but be sure that the fork have replay protection. However, what  Ned Kelly concerning using an exchange is also the option I used sometime and Yobit is good for that.

This your concern even though is something serious from your point of view, its something so simple as its one of the fundamental thing that would be effected even before the forked coin is launched for people to claim (except those who have theirs on exchange site though). All you just need to do is to ensure you have you private key, which you already did, Google how to go about and most importantly,  download the right software or application to claim your forked coin version and you are good to go.
