Bitcoin will be used for big purchases in the future... cars + houses
Bitcoin cash will be used for small transactions.... coffee, smokes, dinner etc
i won't say that bitcoin cash will be use for transactions even for small transaction. maybe its only for bitcoin and we need to wait to see bitcoin is used for many transaction, offline and online. but soon, bitcoin will be used in every where, so be patience

Bitcoin cash will be used for small transactions.... coffee, smokes, dinner etc
why?
please use your brain before writing something like this. why would anyone use Bitcoin Cash for small transactions when there are so many other altcoins with much better features, so much lower fee, faster transactions and lots more! even Dogecoin would be better than BCH for that matter!
yes i prefer to use dogecoin which have lower fee and faster transactions like you said. the other option maybe we can use digibyte and this coins its like dogecoin too. there are too many altcoin which will be good option than bitcoin cash.
