Truly

Your earnings depend on how many people interact with what you post and the more you interact with others in a way that is going to make a real conversation, the more likely it is that they'll interact with you. I notice that most of your responses/comments are just two or three words and are not the sort of thing other people will be able to reply to in return. Once you begin to understand how a conversation works, you will probably find your earnings will move a little faster.

Interact more, then you will earn more. This site is about communicating and interacting with others after all.

the minimum payout is 5 dollars and you have to reach it by the end of the month, but you have to be active in posting and interacting.

You are right, but that is how it is.
