It happens in this way time to time.  I also noticed that spike on Friday and it happened  when bitcoin was going down.  I think one of the whales might have tried to manipulate  Bitcoin Cash . Another reason I think for this pump was coins flipping.  Some traders might have seeing that bitcoin is going down and bitcoin Cash was a bit stable and might flip.  I hold just small units of bitcoin cash, just like you and I intend to hold it for long.
