I had the same question earlier, and I found the following statement by the maintainers of the Electrum wallet very englightning: https://electrum.org/bcc.txt https://electrum.org/bcc.txt In particular this section: > How to redeem my BCC? > BCC wallets will require you to import your seed or your private keys, which can be exported from Electrum. Doing so will expose all your Bitcoin funds associated with that seed to the BCC wallet you decide to use. > Therefore, after the BCC fork, but before you enter a seed or private key in a BCC wallet, you should move all your funds to a new Electrum wallet, with a new seed. You will still be able to use the old seed or private key with BCC, because BCC has replay protection. Wait until your funds are confirmed in your new Bitcoin wallet, before you enter the old private key in a BCC wallet. This will protect your BTC funds from rogue/untrusted software.
