Please find a contemporary (don't look to someone selling alpaca wool socks in 2010 and 2011), stable priced product line in BTC. Anything that I can be confident I will pay +/- 5% of the same BTC for over a 3 month period (I'm deliberately selecting a short period, most currencies are stable for 12+ months at a time when used to price goods and services).
As I understand it at some point there will be no new bitcoin left to mine, and it will just be available as a store-of-value currency -- if I have the concept correct. And the early adopters will be financially rewarded for helping to get it off the ground as they spend their BTC away into circulation.
It's all fun and games until you don't pay taxes, or you try to pay taxes using currency not recognized by the government.
Well, you see, you actually can pay taxes with Euros. In Europe. The USA isn't the only country in the world.
Let's say you are Swiss and are trying to buy something from Amazon and everything is priced in Euro - you also have to convert all the prices in your head. Is the Swiss Franc not a real currency anymore?
I don't know anyone that prices anything in just BTC (it's all BTC converted from USD or whatever, because anything else would be madness) - and I don't know anyone that doesn't peg their bitcoin to what they'd get if they sold it for "real money".
Which makes me think any endgame isn't going to be the utopian, governmentless, money-freedom future I keep hearing promised.
