Many traders are speculating that bitcoin Cash is going to do well in 2018! I do read on reddit that people behind bitcoin Cash are strong than those behind bitcoin core. For me we should allow time to decide the fate of both coins.
Behind the Bitcoin Cash is community China, they are the people always control the price of crypto they like and make the trader on market surprise with them. Example: Antshare, Ethereum Classic, Litecoin are altcoin they like and holding very more, you can see the ratio growth in short time of them very fast but not stable after pump.
