The one benefit that forking off from Bitcoin provides is that the network is already extremely widely distributed so all of those Bitcoin users would also receive your coin. Having the widest distribution possible provides a nice market for your coin. Other than the history and name similarity I don't believe that Bitcoin Cash will become a great alternative to the choices that are already out there.

They claim low fees, well look at Litecoin where I can send money for about 1-2 pennies at most. They can reduce transaction wait times through allowing MORE transactions into each block but the 8MB size will create a cost barrier in the future for people wanting to run full nodes. Also how long until that 8MB size is inadequate to handle the volumes of transactions flooding the network? A simple increase of block size may not be enough to set BCH apart from much faster and cheaper alternatives. Fee-less cryptos will be very popular once mass adoption takes place.

The majority of the blocks are also being mined by unknown miners and the one who is mining the most is just stockpiling his BCH- strange but true.
