Bitcoin: It isn't money, but you can trade it.
There was what seemed to me like a Bitcoin bubble at the end of last year and the beginning of this. I made a nice return on my first trade and then set up what I thought would be a way to "short" Bitcoin for a while. As it turns out, the market at Mt.Gox has been sort of flat since then. So I haven't changed my position.
Stay tuned for more!
If anyone want to speculate about why there was a run-up in BTC value in December and January, please do so in the comments. I welcome your point of view. Remember, the idea here isn't for me to make money. I've only bought $10 worth of BTC. I'm trying to learn more about cybercurrencies and how they behave.
