3 Months Experience in Read cash

Now I am in the 3rd months of using the very best platform named read.cash. But it is very bad experience to me now. At the first stage when the points system work, then I can earn some points & get some $. but after starts of random rewards tip, only two days I got tip. It is very bad experience to me. Why I don't get any tips? I am writing articles, short posts, reacting & commenting post everyday. After all these doing I don't get any tips.
