When I think of one Bitcoin... that is ALL I think about!
To think any further is traitorous.
i.e. Bob says " well, if Bitcoin hits $10,000 US, I'm gonna sell some and buy a new car "
It's unacceptable to think in terms of fiat.
Show some loyalty, and when you talk about Bitcoin, that should be it.
example. Bill says " I have 2 Bitcoins. Gonna buy some burgers now. "
For Bitcoin to have value to be used as a currency, which seems to be the crux of your argument, it has to have value. Where does that valuation come from?
What is the currency widely held as the world currency for lack of a better term?
