I'm curious if anyone has been involved in the BitCoin market? I'm trying to get my head around understanding Bitcoin's application other than what's explained in the Wikipedia. At this time there aren't any retailers that accept Bitcoins. I believe it's more in the realm of a fanbase trade and echange just yet. Interesting concept to have a currency that's not fixed and can be user valued.
A Youtube video on Bitcoins here, Yale law student's paper on legal aspects of Bitcoins here, And here is a site that promotes the use of Bitcoins.
Although I think the idea is unique, I could see market manipulation just like regular money. In this system, just as in regular money markets, there's is both value and volume to manipulate. But, this is probably something we'll see more of in the future though.
