It all depends on how things go, because if the miners will allow SegWit2X to activate, a hard fork will be unavoidable. In the way their proposal is set up, SegWit needs to get locked in, and then activated, and around 3 months after that, the hard fork will follow. If SegWit2X isn't going to get activated before the first of August, the road is free for the UASF to take over. In this case miners might decide to fork off, but hey, everyone is free to follow their own route. And no, whatever happens, Bitcoin won't be at risk, and its price will never be irrelevant -- this isn't the first time Bitcoin has overcome major difficulties....
