I suppose I shall take that as a compliment, Damien, although I am not entirely certain where your ominous sense of me springs from.  Evil is as evil does, as they say.  I had a thought tonight that I cannot quite get square in my mind.  I have so far been playing the exchange with tactics that gradually increased my account in dollars.  If everyone does that, in the U.S. at least, it means that the dollar is valued higher than the bitcoin.  Obviously, if I could pay for most goods and services in bitcoin, I would use the same tactics, but with the goal of buying dollars "low" and selling them "high".  Forgive me if I am asking the obvious.  But I'm curious to know if the bitcoin true-believers trade that way.  That is, selling bitcoins low and buying them high if I understand this correctly.
