I agree with your comment on the further declines.

There doesn't seem to be any indication as of yet as to the miner adoption of BitcoinCash(BCC) and with the exchanges halting and slowing withdrawals market faith is very low.

The point you make on keeping funds in Bitcoin(BTC) is the most sound and safest option but if you do this you will not benefit if both BTC and BCC manage to co-exist and both develop separately due to each having there on utility and different structure.
