Bitcoin reaches six-month high

Anyway, I find the "lack of intrinsic value" argument pretty flimsy. Bitcoin has more use to me than the equivalent dollar value in grain or livestock. One person's "intrinsic value" is another's useless dross. There's always a way your investment can lose value in the eyes of others.

The only real misgivings I have with bitcoin are over the dark bitcoins out there (mined in the very early days). Who knows if they'll ever pop back into circulation, and to whom they belong. Other than that, it's all pretty exciting stuff.
