Bitcoin cash is a fork of Bitcoin. As such, I'd advise for anybody who's interested in making BTC related investments to instead go for Bitcoin itself and not its forks. The reason for this is because of the crazy market cap dominance that Bitcoin has over the crypto market. Nonetheless, there could also be some altcoins worth looking into for similar returns as for Bitcoin investment, with Litecoin, perhaps being one of the such choices.
I would say the future is poor, as with all Bitcoin forks, avoid investing for the long term.
