As for actual value, there is no other value other than somebody willing to buy them from you, and this is true for both BTC and BCH.
There is big difference! Everybody is willing to buy BTC. Only Ver and Wu are willing to buy BCH. Hope that clears your confusion.
It is also not a 0/1 matter of "will buy/won't buy". Price does matter.
I am not a BCH believer, but I would buy say, 1000 BCH for 0.01 BTC, just for the heck of it and the remote possibility of profiting off some future pump that might or might not happen. I wouldn't, on the other hand, buy BCH at the fake prices suggested by the exchanges that actually (say they) deal with BCH. I could sell some though, if it was actually possible (or easy).
