BCH was alwAys going to tank once coins started hitting exchanges. I believe trading to date is just with coins created on exchanges. Prices for BCH went up initially but have tanked over the past hour and I do t think any cold wallet coins have hit exchanges yet.
I completely agree that this has just detracted value from BTC as it's now lost a lot of confidence and this will hold back mass adoption. Why should you buy into any coin when tomorrow it could just fork!?
