I thought I came to that conclusion, no?

 (rereads post) hmm, guess not. You make a good point, and really yes, when it comes down to it, currency change will occur (read: MUST occur). I guess what I mean to say is that the bitcoin would at least reach a state where all trade based on the coin alone, will eventually factor into the whole of trades which will be available in the currency, solely.

 Exchanges will still occur, but I'm hoping it'll eventually transcend currency exchange for the common consumer (and producer, who must exist for this to even work as I think of it) in the Bitcoinomy. Business? No, exchanges will need to occur until the country of Bitcoinia is proclaimed in an abandoned military base somewhere... >_>

(and thats obviously not the point of the Bitcoin; it transcends nationality and borders)

And in the end, we'll see how things truly go. This is not really how I think things will be, but I'm not confident in my theory of what will actually occur. Speculation is for the traders, not the grassroots consumer that I intend to be mostly.
