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.
