"fundamentally flawed?" how so. that is just your opinion.
and why do you think it forked from bitcoin and yet didnt disappear like many other forks have, do you think all those buying it, mining it and using it, think it is flawed? It is the third largest market cap right now. It is hardly flawed if it is functioning that well.
I agree this is a move out of Bitcoin to alts, but BCH went up 50% that is a hell of a move to something that is "flawed" by those who would be leaving at this stage since the herd probably dont even know what Segwit2x was let alone that it is not happening.
none of the other alt coins did anything like that 50% move. So though your point is interesting, it is subjective really.
