It depends on for how long the pump can be sustained. There's no real demand for BCash, someone must be pumping it. That "someone" could be the usual suspects (The Roger Ver - Jihan Wu - Craig Wright connection), or it could be also a random whale group pumping it to, obviously, dump it once people that are absolutely clueless of what's going on, think that BCash is going to reach parity with the real Bitcoin.

It will be fun to watch, the manipulation is huge on any Bitcoin fork because people perceive it as "free money".
