Based on usability, the rates should be more like $20
We've gotten many announcements and many started developments, so chances are that some of those will succeed
But since one of Bitcoin's features is that the amount of available coins will not be adjusted to "necessities", this means that we need to accommodate somehow for all the new people aboard. Which means higher rates, even if they don't feel quite right.
Tough to judge a "rational here-and-now" price, isn't it? And even if one does, the market price will usually be higher than that due to speculation (all commodities). I could guess that a "rational" bitcoin price based on the infrastructure and economy we have now is perhaps, generously, $40. Based on that, the recent peak of $260 was about 6x "overinflated". In June 2011, a "rational" price per
BTC might well have been 50c, meaning the $30 peak was about
60x overinflated. And a "rational" gold price based on practical usability might be less than $100 per troy ounce, but I can't imagine you'll get anyone to sell it to you even as cheaply as triple that, somehow.
