Bitcoin cash after falling down I think still has potential to grow in the next coming years. IMO it will continue to stay and have a price just like that since it is a bitcoin clone and is like ETC for ETH. It will have a price but it will not match bitcoin's price and it will also not match bitcoin's daily volume of transactions. For now I think it is good to invest on bitcoin cash once in a while after it had settled down to a price for long time.
