The growth taking place with bitcoin cash is quiet high compared to the price of bitcoin which is in decline. At some point the growth percentage will be similar in value, which might cause the chains to grown in a mutual manner. Hoping for this I would hold whatever the asset maybe, as the future growth of bitcoin as well bitcoin cash will be bigger than the other crypts.
To be honest, I doubt this new BCC would just behave like some of other altcoins, which at early the price will be pushed due to market hype, but later when it comes to the realization of the underlying value, they dump it at the end.
A way I analyze this is taking ETH/ETC split as a reference, the network hash rate of both cryptocurrency and the price is highly correlated, roughly around 12:1 ratio. Meanwhile, the BTC/BCC network hash power ratio is around 25:1, but the price is at 7:1, seems like overpriced for me, and I haven't considered the actual usage of the BCC, which is actually 0 now compare to BTC which widely accepted by millions of merchant.
Probably in next few hour, once most wallet and exchange started to accept deposit/withdrawals, might see quite a number of people dumping their BCC.
Anyway, this is all my opinion, could be wrong.
