My question is, if I import the private key of the 1BTC addy to the "electroncash" BCC wallet is that all I need to do to move the BCC without fucking up my BTC?
After this, you can import the private key to access your Bitcoin Cash. I don't trust Electron Cash on my normal computer though, so I used it in a VM (Virtual Machine) to be safe.
Next, you can do the same for Bitcoin Gold and Bitcore (I used Coinomi on Android to import those private keys).
