This got so newbies confused into buying Bitcoin Cash, thinking it was the real Bitcoin. I think o even saw some threads about that confusion.
It's not hard to confuse/misinform newbies. Bitcoin Cash made that claim because Bitcoin decided to implement segwit (or some other BIP) and some rebels didn't
like it and forked Bitcoin Cash. In that sense they are the "Original Coke" while Bitcoin changed and became the "New Coke". So they are technically correct.
At the time of the fork everyone who owned Bitcoin got an equal amount of Bitcoin Cash so no one got scammed. Some people still own Bitcoin Cash and don't know it.
I sold all mine right after the fork.
