BTC is most definitely up, but yeah the dollar is also weakening daily.

Why not both?

In my non-expert read of things, bitcoin is probably up due to network effects, usage and speculation. As digital rails are built for USD and USD tokens, we may actually see both go up relative to other things (or at least slow USD’s rate of decline).

I can buy more tacos with Bitcoin this week than I could last week. The number of tacos I can get for dollars hasn't changed.

I’m sure

Yes.
