But they are using everything they have right now and aren't able to drop BTC below $6200ish and raise BCH above the mid $1300 range with all of their might.
This is on top of the expected market correction after the fork, mind you.
It may be ok to move a little into BCH vs. the alts, since the alts seem to just be sticking to their usual patterns and BCH is climbing. You'd just better to be ready to bail out of BCH at a moment's notice because if there's a sell off by the whales manipulating BCH, it could get very ugly very quickly.
There is more to life than just quick profits.
