Take care when claiming coins from those forks - even if only for transferring them to an exchange. Wallet software for those altcoins usually come as an unsigned, unverifiable binary and ask you to import your existing mainchain private keys (explicitly or as wallet.dat). Doing so is a best way to lose your BTC should authors get hold of those keys.
Much safer solution is to craft transaction offline on a separate VM (using BCCSplitter [1] or altcoin wallet) and then posting raw transaction using altcoin's blockexplorer or yet another instance of altcoin wallet software (not containing any private keys).

- magnat 9y agoIt depends. If you import whole wallet.dat into altcoin wallet, you share both present and future (next 100 or so) private keys with the software. If you transfer your bitcoins to new address provided by existing bitcoin wallet, chances are the altcoin wallet also has a private key to those addresses. To be safe, you'd have to transfer existing bitcoin funds to completely new wallet. Also, for privacy reasons you would need to make as many transactions as UTXO you have, which means paying a hefty fee tens or hundreds of time depending how much you use your wallet.
