hmm. still confused and not sure I'm going to be flipping coins back and forth. If I mined them, and they were free/pennies, might make sense.
If one has an offline wallet with 1 bitcoin that cost me $1000, for example
and then the fork occurs...
How do I then have 1 Bitcoin Core and 1 Bitcoin Unlimited?
If I do nothing, my wallet still remains - when I scan my QR code, what will it tell me?
Will my old Bitcoin coin show up as Bitcoin Core or Unlimited or Classic?
If I import this offline wallet back into an exchange, what does it do? Where does it go?
Think of a fork in a path. Both ways that start with the fork have the same path before the fork occurs. So if you had 1 BTC before the fork it will be on both paths.
If you will scan it or send it to an exchange it will depend on the scanner/exchange what it will show. But in most cases it should show both.
