anticipation of widespread mainstream acceptance.
This is the problem. It should primarily be when merchants actually accept it that the price goes up - and these price rises should be primarily caused by people buying coins to spend at merchants. Unfortunately, it currently doesn't seem to be about that at all.
“I think we are seeing fiat currencies in a hyperinflationary collapse against Bitcoin.”
Bitcoin is still pretty much irrelevant relative to the gold market. We're talking about 1 to 10 billion dollars being traded per day, which is irrelevant relative to the total supply of dollars and will have next to no effect on the dollar's strength.
As for "hyperinflation", that is simply not happening and I consider it misleading (arguably even lying) to suggest that the US dollar is experiencing hyperinflation.
The dollar may well become weaker, but if so there's no point trying to pretend that Bitcoin users somehow played an important role in this.
