Do BTC-friendly merchants constantly change prices as the fiat exchange rate fluctuates?
As the value of bitcoin fluctuates against fiat currencies, how do merchants price their goods and services (that have a stable fiat value, e.g. shipping) in BTC without constantly changing the BTC value to reflect the equivalent in fiat?
Also, did I correctly not-capitalize “bitcoin” in the first sentence? I'm referring to a mass of coins, not the system.
