I don't think there is a proper theory that deals with bitcoin futures because with price fluctuations every time makes traders must be ready to accept all forms of risk in the future.With difficulty making a prediction about bitcoin exchange rates.
Nothing is predictable about this world and so is bitcoin. This amazing coin has its own secrecy that cant be revaluated by anyone at any time. you may come across different lines and statements talking about what is the future of bitcoin and how it would be moving onwards. Keep best practices in field. You would be seeing best future with bitcoin.
