Can someone give a concrete example of themselves using Bitcoins for something other than speculative trade ?
Silkroad. It has consistant business and I know people who have used this website. However, it fails to use bitcoin as a currency in the sense that other stores use dollars as a currency. The prices on Silkroad are adjusted to mirror the USD->BTC exchange rate dialy. And, I would suspect that the majority of the users are buying bitcoins to buy goods on Silkroad, and that venders on Silkroad turn their BTC back into…
Anyway, a currency that people buy to use in particular markets is possibly a way that money got started in the first place. People traded for a currency to use in a (physical) market and then traded that into different stuff that day. Eventually, as things stabilized they might have been happy holding some money.
If bitcoin became commonly used as a way of transacting, but not of storing value or denominating prices it could still be a good enough starting point.
