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?
I don't know mate,and no one really knows answer for your question.
But I will say the chances are very less and because I can see no potential on bitcoin cash,it is just a clone coin made from hard fork of bitcoin.But the price of BCH is still high in prices when compared to other forked coins but I don't think it will last long.Maybe the price of BCH will be less at end of 2018 than the current price.
I will pick 10% chances are there for BCH to hit $10K at 2020.
