BCash is a dead horse. You need to look at it in terms of BTC price and not USD price to see the bigger picture.
Here's a snip from BCH/BTC pair chart on CoinMarketCap.
BCash is an ever declining asset, while it might give you some profit in short term, it's not a good investment for long term, and let's be realistic here, almost every other alt coin has had a similar level of increase if not more in past couple weeks, why would BCH not.
BCH died the moment Roger Ver and his team dug their own grave by claiming that BCH is the real BTC, and to top it off they led the efforts to mislead newbies into purchasing/using BCash on Bitcoin.com wallet by claiming it's Bitcoin.
