Bitcoin Cash is an altcoin, that is getting no support at all by no one beside its creators. This is what we can call a big fail. Being an altcoin, I see no reason to compare them...
To those comparing the two, they know what they saw and they also know the basis for such conclusion but for me, I have not even claimed my own BCC with all the paparazzi and I am not sure I will but it seems the popularity of BCH or BCC is just for a while and after the week of August 1, it just seems everyone decides to close the chapter on the controversy but I wish it will succeed so that doubters would at least know they are wrong on this one.
Yes, BitcoinCash is just a new altcoin that was ripped off newly from the main BTC, so you shouldnt expect it to start competing with BTC since its still new in market. This is just its first month, so lets wait and see how things roll out in coming months. Personally I do not see any big potential with BCH as bitcoin itself is updating itself to scale high volumes. So, BCH may fade out in quicker times.
