This is impossible to do, we must remember that the price is an aggregate of what everyone in the market is thinking about the price of bitcoin, this means it is not controlled by a single person or indicator but by millions of people all of which have contradictory beliefs, needs and wants, so predicting accurately what the price will be over the long term is not something that can be done, you could make some calculations which could give you a range, but that is as far you will be able to go in your quest.
