I see they have different rates for different sections, even for upgraded members, it is still do not have fixed rate. For instance, i post is GPT sections i only get 0.5 cents per post, but post in technology sections, i can easily get up to 2.5 to 3.5 cents per post. But each month the rates for the sections changes, it will not always giving high rate for the same sections, you have to try to post at least once in every section to see which section is currently giving the highest rate.
