I do not know what Bitcoin cash means since I am a newbie. I haven't sold anything yet. But I would be glad to know more about Bitcoins ans how it works! Looking forward to experience that first hand. 
Think of it like this: there was a fork in the road, bitcoin went to the right, bitcoincash (an "altcoin") went to the left. The real problem with $bch is when new people first get in to bitcoin could end up buying what they think is bitcoin but really bitcoincash. Since the addresses are similar but not compatible, you could potentially end up losing your money if you sent real BTC to a BCH wallet.
This confusion is like a toxic apple.
