Profit sharing is a new-age model which does not use a fixed based earnings/time span model where you are entitled to receive a return in a fixed amount of time. With the fixed based earnings/timespan, new income needs to come in constantly daily or else the program will run out of funds to pay out to the members leaving them with a partial or total loss. In LightHalzen, you keep earning on your deposit till you reach 150%, be it 2 days, 10 days or more because the funds never runs dry. This way the risk of losing out next to the fixed earnings/time span model is next to zero.
