I have been playing with FAP demo's for a while now and just came up with an idea.

What if you could invest a small amount and still trade with real money?
Less risk, Less Work...

I personally don’t have a lot of money to invest into this sort of thing. At least not until i make enough. But what if I was to design a website that enabled users to be a part of a much larger investment pool.
For example. You could sign up and invest a small amount like $50, along with a few other users who also invested various amounts of cash. Once the group had enough we would start trading.

Lets say that the group has accumulated $500 to trade with.
Of that $500 you have personally contributed $50.
Your share is 10%.
After a few days that $500 has turned into $1000.
Because you had a share of 10% you now have $100.

This could potentially happen weekly. Each week you could choose what amount of money you want to contribute. Depending on the amount you deposit depends on how much you stand to win/lose.
The higher your share more you stand make.

At the moment this is just an idea and I plan to implement this in the near future for family and friends. Would this be something you would be interested in? Should this be public?
