Yes.
The fundamental value that Bitcoin presents doesn't change because a sub-reddit shuts, or some corporations stop accepting BTC.
The network is in better shape than it's ever been, resistant to all sorts of attacks launched against it by some interested party or parties over the years (I wonder who they could have been.... )
As long as Bitcoin holders do well at evaluating the risks we're presented with in the shape of this latest attack (BU), we shouldn't have a problem in the end.
It's a big if, but I believe we can do it. Weak hands will bail. But those who got it to begin with will use the same instincts to find the way out, as there is a way. BU is a serious threat, no doubt about it, but we can overcome it. On the other side, great things await.
