Description [in detail]

1. Use your psychoDollars to purchase the "the big nothing".

2. When you buy the object in clicking on the buy button, the price will increase, if you sell it, it will decrease

3. If you think other people will buy, then you should buy before them. If you think they will sell, you should sell before them.

4. If you think the price will go down, you can make money in selling short the object and if you think it will go up, you simply buy it.

5. Exchange the psychoDollars back into USD.

There are no transaction costs, however there is a spread (details in the how it works section) when you buy and sell. So it is important for you to play close attention to the chart and try to predict how other will think that you will think that they will think.
