Bitcoin halving isn't all about the price rise. It's not like because we just crossed halving, doesn't mean the price would shoot up. The theories of other people (including me) that the price would shoot up on halving is wrong (as we all have seen). It will surely rise in the future but it wouldn't shoot up right after halving. And also, I'm pretty sure "worst things" aren't waiting for us in the future.
Why should it? Most (big) miners are still making profit at the current price and there's no sudden surge of demand good enough to cause the price to continue increasing despite what we've all seen in the last 2 months. It is perfectly possible that the halved block reward will increase the price over time, but expecting it to increase right away are just unreasonable.
