How do you earn in myLot exactly? I dont really get the system.

They use a system that is very complex which you are not meant to understand. that way there's no way to cheat the system. They talk more about it in their FAQ. Since you are fairly new on here, it would be good to read the entire FAQ because it is loaded with information and will help you to know what you can or cannot post on here as well as explain some of the other aspects of the system which you will have questions about the more you use it.
