> 2025, and even Bitcoin conferences are still posting their ticket prices in fiat.

Just need to do a stackference:

No entry fee but you need to put up sats to speak or ask questions.

I think Bitcoiners use the fiat cash much more than they use any kind of plastic.
That is at least a small step to privacy. Cash, even fiat, leaves no trails.

And yet, we're doing very little to "stop using their currency".  

Bitcoiners as a group, on average, use fiat 99.9% more often than Bitcoin.  

And don't give me that Gresham's Law and paying taxes bullshit.....  It's purely laziness and a preference toward convenience.  

2025, and even Bitcoin conferences are still posting their ticket prices in fiat.  It's shameful AF.
