There are so many coins and they depend on luck, marketing, development, and a ton of different factors. I don't think that analysis of graphs alone is anything but a guess game unless we are talking about large changes in already very popular coins where market is already huge and pure statistics come into play. This coin is around #300 and there are hundreds of other coins there with probably very similar graphs. With 1000 positive "predictions" there is a good chance that at least some of them will be true.
