Market price is hard to guess, at least we should have a prediction because we hope the high price of bitcoin. I predict bitcoin price based on news and some references. Usually if I predict the bitcoin price is not too high and not too low, I take the middle price. If I predict the price is too high it is frightened to miss, because it does not make sense. Especially now that many people want to monopolize bitcoin, they create negative news that makes bitcoin price difficult to predict.
