bitcoin cash should be considered an altcoin with an airdrop much like clams. A snapshot is taken of the original bitcoin blockchain and the balances reflect on the forked blockchain.
If they really wanted to do this they could have just created a brand new altcoin. However they are definitely trying to steal bitcoin's name and image. They know that if they just created another altcoin they'll gain no publicity because there are so many better options out there that are better than this.
They are going through with it even though they seemed to support segwit2x. If they made a compromise then i wouldn't be angry at all, but now they're just trying to destroy bitcoin by having an unnecessary hard fork that only has speculative value and nobody is going to accept
If so, why the leading brand doing this? I don't understand. After all, thanks.
