That was my point, in essence. Crypto fails as currency because the people in that market don't want it to be less volatile, making it bad for typical currency uses.

While yes, the relative values of currency fluctuate over time and in relation to one another, it's orders of magnitude less and driven by far more predictable and based on actual real world factors. Instead of Fomo, whims, market whales, and indecipherable white papers.
