i just got my BCC out of Jaxx and i want to share this with you. It is pretty easy and took only 5 Minutes. I think i am not the only one who waited and it was to risky for me to do any try outs.. but this one is really simple and even for me as a newbie who did some stuff wrong in the past it took 5 minutes
Go to
https://wallet.btc.com and create a new BTC Wallet.
Now you have a BTC and Bitcoin Cash Wallet and you can choose your wallet (Cash or BTC) in the upper left.
Just choose Bitcoin Cash because the default is Bitcoin and go to settings.
Choose import external wallet and choose "BIP44 Compatible Wallet"
Now type in your Backup phrase you have created in your Jaxx Wallet. After that your BCC will be shown and you can import it. After 5 Seconds it is done. Now you can send your BCC to your Bittrex/Bitfinex Wallet or do whatever you want with it.
