Gain is a "game" that lets you predict whether the currency exchange between two currencies will rise or fall. If you prediction is correct then you gain points. If you are incorrect, you lose points. The sum of your points from 5 different markets become your total score. Your total score decides your place in the weekly user board and depending on your place, that is how much money you gain. You are allowed to cash out when your balance reaches at least $30. They do send it in a business transaction so fees will be needed. I cashed out at $30.27 and received $28.79.
