Thanks to all of you for the positive comments.

Nothing is random is BitStratego: you choose your "target" and for how long your investment is going to be active.

Let's say that one user deposits 1 BTC and selects a x10 target and a duration of 1000 hours.
After the 1000 hours, the investment has earned 12 BTC, so the user receive a 10 BTC payment, the surplus of 2 BTC is distributed among active investments.

In another example, one user deposits 1 BTC with x2 target and a duration of 10 BTC volume. After 10 BTC volume has been distributed in dividends, the investment has earned only 1.6 BTC, so the user lose and the 1.6 BTC are given to active investments. 

Just imagine how many strategies can be played and the many different outcomes that can happen!!

A x1000 win is possible but quite difficult, I think.
