I am very skeptical regarding any possibility of btc price prediction not only for the next month, but even for the next day. And even if someone really has such ability to predict btc price, why would he share these predictions with anyone? He would rather silently buy and sell and become superrich. Different thing is price manipulation by big whales. They can in some way predict the price of btc, because they can directly influence it by their actions. But this is not a typical prediction by analysis
