About:

Why It Could Works:
Users add products listed on Amazon, as a cds,music system, furniture, and so on. Each item added becomes a "stock" which has a value. If a product's Amazon's sales rank improves, its stock price goes up. And vice-versa. Traders buy, sell, short, and cover. Products are grouped with tags and compared to other tag groups. Just for signing up you get 10,000 smarket dollars to being trading. It's free to join, and it's a good way to learn about stocks and prediction.
