Bitcoin Cash forked off Bitcoin in August. Two different cryptocurrencies. If you owned Bitcoin on 8/1/17 you received an equal amount of Bitcoin Cash. If you use an exchange like Coinbase, you should see it in your account (as of last week). There are some differences between the two, but you got to research that yourself (far to long to post).
As I’m typing this, Bitcoin Cash is about $2,400, Bitcoin is about $14,000.
