Due to the controversies of the BIP 91 proposal, Bitcoin mining provider ViaBTC and other supporters are planning a hark fork on August 1st. It will be called Bitcoin Cash with a block size of 8mb.
Now, it would be up to debate whenever this separate chain becomes successful in the future and it gets the attention from major exchanges, businesses, and startups that support Bitcoin.
Do you think Bitcoin Cash might overcome the original Bitcoin we know and love in the future? Or will SegWit2x prevail and render other forks useless?
I would like to know your opinion about this

There is a poll in discussion thread about the possible outcomes of Bitcoin Cash, there is a coexist option, bitcoin and BCC would coexist with latter having a lower price than former, right now IMO it is not about coexistence, BCC ≠ BTC, so an altcoin and this is what defines BCC now, a cryptocurrency that is alternative to bitcoin, so many alternatives, not equal, so not bitcoin.
Would BCC overcome bitcoin in future is a tricky question to answer at this point in time. If I am right ETH, Bytecoin, Monero, Zcash have gone through forking and some got the better of originality and some got the better of the forked version.
No comparison between these cryptocurrencies and bitcoin, globally accepted first crypto, 9 years, $42 billion cap. Would a forked version of bitcoin be able to get a better of these stats, there is majority, super majority, economic majority, consensus. Let's see how it plays out.
Right now Segwit activation is what matters and personally I don't agree with hard fork three months after that. No efficient planning, lack of developers, lack of revewing by proficient developers, lack of testing, how much of all these can be achieved in three months. If I am right BU had messed up with their coding. A hard fork is not backwards compatible, messed up, and it is messed up. It was six months and then three months and now UAHF in midst of Segwit activation, what's this rush all about?
