whether or not a business accepts silver and gold (or maybe barter of other goods/services) as forms of payment is a better Liberty litmus test.
Bitcoin, while growing in popularity and independent from other money, still suffers from the fact that it is basically intangible.
I am guessing that most people, Liberty minded or not, don't like the idea of electronic money any more than FRN's.
Also, when SHTF will people still be able to use Bitcoin for trade?
Keeping some silver/gold coins, extra ammo, or other barter-able goods in your Bug Out Bag and emergency stores seems to be the safest bet.
