Even I think bitcoin cash is not worth to holding, it's better to sell it now before its price falls hard.
I'm not sure the price of bitcoin cash will increase.
Many people rely to trading because its the sense of bitcoin.Its value is increasing and decreasing time to time so it is better if you trade your bitcoin when the value is high and dont wait for to much for the value increasing just trade it if you know that you are satisfied on its value.You dont know when it will increase or decrease thats why think of it.
