Its just another altcoin,miners chasing profits will benefit for a few months but then again it doesn't have any potential for growth once segwit,lightning etc comes into party on btc
Quite true but don't forget supply for BCH is very limited (less than BTC supply as more than 3-4 million BTC already lost forever so BCH also lost with them), if BCH somehow increase up to $1200 or more then many miners will switch their hashing power which results more price increase and BCH may become strong competitor for BTC
