It took about 2 years for bitcoin to increase value from $1000 to $10,000. What is the chance that bitcoin cash would also go up to $10,000 in 2020?
Nobody knows the true answer here
Though it might be a clone coin but still it is faster and has less fees than Bitcoin. When Bitcoin cash was at $300 everybody were saying it's a scam, pump and dump etc but now see what happened. Smart people made money in the Chaos and some ethic fellows kicked themselves for not buying. This is why anything can happen in cryptocurrencies.
