My opinion is that Bitcoin Cash protocol edits should have happened a long time ago. Like the split in Ethereum, both block chains are going to hold a value, when transactions on BTCcash get cleared in minutes without the thousands of unconfirmed transactions we see with the current protocol, people will start to shift, especially the merchants that suffer waiting for purchases to clear. Ultimately though BTCcash though faster than Bitcoin, will still lack the ability of Litecoin and DASH for rapid transactions, and will find it hard to maintain a secure mining network. Why spend the power(electricity) to mine 12.5 coins worth $30 when the same effort could earn you $2500/coin.
