It could descend to $8 000 USD, but Bitcoin Core has so many developments going with RootStock, Lightning Network, atomic swaps, Segwit, etc. that I think Bitcoin Cash will fall by the wayside as, albeit, a decent altcoin, but not the king of crypto. BCH attempted to take over, first with a large-scale attack back in November, and more recently, with a surprise release on Coinbase that was suspicious and involved insider trading (which is, admittedly, perfectly legal in cryptocurrency). Ultimately, their attacks on Bitcoin have failed thus far.
Within a month or two, the buzz will be back on Bitcoin and its exciting improvements.
In the meantime, huge gains are to be made in the altcoin market.
