I've heard 650k for one BTC. Is that true?
In the Bitcoin-kills-governments scenario I think it's 1 or 2 orders higher. I would expect people to choose to hold a higher % of their wealth in cash (bitcoins) when it wasn't being debased and to be wealthier in general.
Yeah, always todays dollars. We're in the unfortunate situation of having the dollar as the best reference. But if Bitcoin is the money then 1BTC will buy a hell of a lot more than a 5br house in a decent area.
My thought is that gold is a better reference than dollars. In a "bitcoins are the worlds currency" situation and the total value of all btc equals the total value of all the gold in the world then a back of the envelope calculation puts 1btc worth about 476 oz of gold, or $714,000 at todays dollar value. We probably have a few more months to go before we get there.
