BTW, whatever that thing calculates, the result looks just like "lol I took the first derivative of the logarithm and did some magic re-scaling." I don't think this can predict the future. 
With bitcoin, it can. Tea leaves and astrology can too. Anything can fairly accurately predict bitcoin, the only condition is that enough speculators believe it can, and get the same "analysis" (I guess that rules out tea leaves) and therefore act upon the prediction so it will automatically become true. After all, to predict bitcoin exchange rates, you have to predict the actions of other investors, as thats pretty much the only variable. If enough speculators believe the moon phase will have an effect on bitcoin, then it will.
