@chucky732 @bentusison and others if you want to speculate about future value of Zcash there is a thread for that: Price Speculation
Otherwise the speculation that “Zcash will be worthless” or “the value is going up/down/whatever if they don’t fork” are off-topic for this thread.
And there is no evidence that Shapeshift or Changely have paused thier conversion services for anything to do with ASICs or otherwise.
