Bitcoin cash will not replace bitcoin. We can speculate all we want but we all know that bitcoin has taken root downward and it will be impossible to undone all bitcoin has achieved over the year!
See my prior post. You are not factoring in the eventual $billions of SegWit booty available to miners who revert BTC to Satoshis protocol.
Money talks. UAHF bullshit walks. Whales understand that if we allow Core or anyone to mutate Bitcoin without a decentralized market process, then Bitcoin will be just another altcoin.
Sorry I think you are dead wrong. And you will lose all you BTC to theft by the miners because you are not paying attention.
