Hello all...  I'm creating an offline Ubuntu 16.04 machine with just bitcoin-qt installed.  My intention is to get a running Bitcoin Core client going on the machine and then remove the network interface and never connect it again to any network.  Then I want to generate BTC addresses and private keys on that offline machine just for saving BTC to those addresses.

Question: If on this offline machine I make (for instance) two addresses with their private keys in bitcoin-qt and only use one for funding BTC amounts and the other for funding BCC amounts will there be any problem accessing/spending the BCC at a later time by simply importing the corresponding private BCC key into (for example) a Bitcoin ABC wallet on an online machine.  In a nutshell I guess I'm wondering if the addresses/private keys are compatible across the two networks so a private key and its address can be used without issue with BOTH BTC AND BCC regardless if its created in the first place with a BTC Bitcoin Core or a BCC Bitcoin Core.

I probably did not ask that well, but I hope my point is understood.

As a follow-up to this...if the address/key pairs will work fine on either network, am I correct in assuming that I could import the keys into any offline wallet of BTC or BCC in the future to do offline signing of transactions?

thank you!!!!!
