what else is there to say?
Quite a lot, if you're implying that that bitcoin is currently enjoying a more stable valuation than USD.
The 10-day moving average (10MA) for bitcoin has fluctuated from 14.3USD to 12.8USD. That's about an 11% fluctuation.
Compare that to something like the USD -> Euro exchange for the same period, 0.713 to .7028. That's about a 0.9% fluctuation.
I'm not going to say it's bad or good, right or wrong, all I am saying is consider a 10-fold difference in pricing volatility.
Look at the long term value of the dollar. It has lost most of its purchasing power since inception. That's like comparing bitcoin to a pile of dog shit.
