I guess you are not even listening to yourself. You are talking abut predicting the future like it is some kind of skill any human being should have. No one knows what the future holds or what the market is capable of in the next minute.
To answer your question, there is no tool to predict the future price of anything. You can only find tools with which you can use to blend with the trend.
I also believe that there is no tool to predict the future but of course we are the one who are affecting the price of the bitcoin. We may not diretcly predict the price of the bitcoin in the future yet we must know how we can affect to the price of it. By trading, holding and selling coins it can affect the price of bitcoin and as we know bitcoin price os not stable so that time by time it change. There is no tool to predict future price but we can learn how.
