I will choose Bitcoin. This is the currency here to stay for a long long time. Surely, in a year or two it will establish itself in the e-commerce market and then you will be able to buy from bitcoins, which you cannot do it by keeping gold.
Perfectly agree, the average gold user probably is a bearded fat guy living in a bunker.
The average bitcoin user is a well educated, innovative and enterprise oriented tech guy.
I don''t think the looks and education has got to anything with it. It is all about mentality for accepting new things and to become part of innovations, rather than living in a usual routine. Bitcoin is attractive to user because of its prices. These users will be gone when bitcoin prices comes equal to fiat currencies.
