I agree with a bit of what you said since and the combined value does add up to around 3K, didnt think of it that way. Maybe Bitcoin cash will grow when bitcoin drops but I doubt it since Bitcoin cash is just an alt coin and nothing special. I will predict that a pump happens to Bitcoin cash with all this hype and then when people realise the truth the coin will starting dropping and will probably drop to 200 or somewhere like that.
An interesting event, especially with all of the FUD and hype, but it was a shame it didnt really do much.
I believe the reason why the BCH has its higher than expected value right now is because that many people cannot sell them due to exchange restriction (such as from Coinbase) or problem in the selling process. Once people have access to their BCH and once people can freely sell their BCH, I would expect its price to drop significantly, and maybe, to double digits.
