Many experts are currently refer to bitcoin Cash as one of the altcoin on bitcoin blockchain. The only difference it has from the traditional altcoins is because it share transaction history with Btc. I read many comments on it on reddit that people are going to dump it very soon and that created fear in my mind not to invest in it.
It is your personal choice to keep the coins or dump it as soon as possible,since it is a reward for holding my coins and never really invested in it i am happy to hold for a longer time and if i feel like the price is going down,then i might dump some coins,it all depends upon how the market is reacting in the coming weeks and it is listed in major exchanges around the globe,so i think we could see some higher valuation in the future.
