The longest chain is real bitcoin.
That isn't how _any_ version of the software release by Satoshi or any version ever after worked. That isn't how Bitcoin is described in the whitepaper either. You're just regurgitating a broken model of Bitcoin pushed by people trying to take it over like Ver and BU-- who all quickly abandoned that approach when they found it wasn't working for them.
From my understanding, there is a high likelyhood that 2x will fail on operational and technical grounds alone. Do you think this is a pretty accurate assumption? I really hope it does, but could it actually succeed with the new developers?
