Im a bit confused...so, when I redeem a physical bitcoin after the fork, will I be redeeming just the BTC? Or will I be able to redeem that coin for BTC and Bitcoin Cash?
If it was funded prior the the fork, it will have 2 balances - one on the BTC blockchain, and another on the BCC chain. So yes, you theoretically should be able to redeem both.
Personally, I'm a bit wary of replay attacks after googling around (Remember ETH/ETC fork?), but guess we'll see
soon...
