"1 BTC = 1 BTC" emerged, IIRC, as a commentary on/response to fiat-obsessed bitcoin speculators who only cared about fiat value.
if you are a true bitcoin believer then BTC is the proper unit of account---never any kind of fiat money. fiat money is just a temporary reference. purchasing power is not and never was the definition of a bitcoin, nor should it ever be.
1 BTC = 1/21,000,000th of the max monetary supply, period. if that's not how you're oriented, then you're still stuck in the old paradigm, and you don't value bitcoin as an economy unto itself.
People arguing to keep the ChipMixer payments at their current rates who are trying to get a bigger paycheck, they know that the campaign should decrease the rates and probably want the discussion about it to stop. It's logical, though a bit too smarmy.
i just think all the open speculation lacks tact. it feels icky. people with common sense understand the underlying economics and can reasonably expect what's gonna happen. but i don't see the point in making some public spectacle out of it.
