"Bitcoin is a currency."
Fact: Bitcoin is crypto-gold, not crypto-currency. 99% of bitcoin users hoard or speculate. It has zero prospects for ever becoming a currency, but it's a great speculative investment.
Gold IS money.
The first country to back thier paper currency via BTC will make it rain. One large problem is only three countires are not owned by the central bank and I doubt any of them would be interested in doing this. Although when the debt bubble goes pop... people won't be to interested in paper.
